How to calculate how much timber is in 1 cube?

We offer a simple calculation so that you do not get confused with the question of how to find out how much timber is in a cube. These calculation options are suitable if you know the dimensions of the timber. For example, let's take a beam 260 x 260 x 6,000 mm (6 meters). The same can be done for timber measuring 3 meters, 4 meters, 5 meters.

Formula for calculating the volume of timber:
100mm · 100mm · 6000 mm = 0.1m · 0.1m · 6m = 0.06 m3

Formula for calculating timber in pieces:
Beam length - 6 meters
1m3 / 0.06m3 = 16 pcs/m3

Difficult? Apparently not! But if the calculation is difficult for you, just use our table. The table contains calculations for all known sizes of timber, which are given in GOST 8486-86.

The page contains answers to simple questions from people:

• How much timber
• How many cubes of timber
• How many cubes of timber?
• How much timber do you need?
• How much in one cube
• How many pieces in a cube
• How many bars are in a cube
• How to calculate how much timber is in 1 cube

Why know how much timber is in 1 cube?

There are two reasons for this:

1. You can immediately calculate the total price of the volume of timber you need. To do this, you need to know the volume of 1 piece of timber, the price for 1 cubic meter and how many pieces in total you will need to implement your plans.
2. You can calculate the total number of lumber units needed for the project. And this can be done by knowing how many cubes are required for the work, and by calculating the number of pieces of timber in 1 cube.

Repair and construction work often involves the use of lumber. But shops and timber trading centers often sell them not in pieces, but in cubes.

Everything is very simple and fast.

Method for calculating edged lumber

• a caliper, tape measure or folding m; if the length parameters of wood products are known, you can limit yourself to a regular ruler;
• calculator - suitable mobile phone, smartphone, if problems may arise with mental arithmetic;
• a piece of paper and a pencil - to record the results of calculations, how many boards are in a cube.

1. Volume = Length × Height (product thickness) × Width.

To prevent confusion when converting cubic centimeters to cubic meters, it is more convenient to immediately record the measurement results in meters.

For example, 0.132 cu. m = 6 m × 0.022 m (2.2 cm) × 0.10 m (10 cm).

Now, to determine the number of planks in a cube, you need 1 cubic meter. m divided by 0.132. The result obtained (7, 5757) when purchasing timber must be rounded to 8 pieces.

This method of calculating cubic capacity is also suitable for timber. This way you can determine how many cubes of timber you need to purchase if you know the required number of products, or, conversely, determine the required number of cubes.

How to calculate the cube of an unedged board?

To determine the required volume of timber, the easiest way is to carry out calculations similar to the above method. Only the final result needs to be multiplied by 1.2 - a correction factor. From unedged boards you can get no more than 70-80% of edged ones.

The width and thickness of each product are measured taking into account its further processing. The technique will help determine the number of cubes of wooden products needed for work, if the final result is planned for their further processing - trimming.

When purchasing, the widest and thinnest boards are measured to obtain an average width. If the width of the lumber at the butt is wider than at the top, the arithmetic mean of their dimensions is used without taking into account the bast layer or bark, rounded to 10 mm. In this case, fractions from 5 mm are rounded to the full 10 mm, and fractions up to 5 mm are not taken into account. The length and thickness of lumber are measured in the usual way. The volume of timber is determined according to the usual scheme:

• the volume of one product is calculated;
• the total cubic capacity of purchased timber is determined; According to GOST, correction factors are used: 0.96 – for lumber from coniferous trees, 0.95 – for lumber from deciduous trees.

In addition to the piecemeal method for determining the volume of unedged lumber, the geometric method can be used.

Requirements for a package of unedged timber:

• lumber is laid tightly, without overlaps, in horizontal rows;
• on one side the ends of the boards are aligned;
• all sides of the package are strictly vertical: according to GOST, the displacement of individual products outward and inward should not exceed 0.10 m;
• The package of lumber must be the same width along its entire length.

Then the volume of the package is calculated, the resulting result is multiplied by the coefficient:

Before starting construction, it is necessary to determine the required amount of material. This parameter will be needed for the purchase of raw materials and products; in most cases, it is also involved in engineering calculations. In the article we will analyze how many boards are in a cube.

Types of lumber

To date wooden crafts for construction are presented in a wide variety of variations: components for the construction of walls and individual structures (beams, logs), various panels (fibreboard, chipboard, OSB), elements for finishing and cladding. Therefore, it’s worth starting with what the boards can be:

How many boards in a cube of any type are determined in the same way, regardless of the type of wood and the degree of processing. Exceptions are unedged boards. Next, we will consider calculation methods.

Concept of volume

Everyone knows from school that 1 m 3 = 1 m x 1 m x 1 m (length * width * height in meters).

Since the elements of a batch or type have the same dimensions, how many pieces of boards in a cube can be determined by knowing the volume of just one. At the same time, it is not necessary to imagine a physical figure with sides of 1 meter; the concept hides the actual volume of the product. It is used in purchasing and selling, calculating total construction volumes and constructive calculations.

Determining the quantity

Everyone knows that boards 1 meter long are used extremely rarely; their main working length is 3, 4 or 6 m. It is worth considering that lumber is produced in production with a length reserve of up to 10-25 cm. In some cases, the seller neglects this size, but in most cases it is taken into account in calculations. Therefore, pay attention to this so that there are no questions about overpayment. Height and width are indicated exactly in millimeters. The final dimensions look like this: 25x200x6000 (height*width*length in mm). To convert the value into meters, you need to divide the values ​​by 1000, we get: 0.025*0.200*6.0 (m). We multiply the values ​​among themselves, we get: 0.025 * 0.200 * 6.0 = 0.03 m 3.

Since all boards have the same appearance and parameters, we determine how many boards are in a cube: 1:0.03 = 33.33 pieces. Rounding to whole units, we get 33 products. Here you can calculate the cost of 1 board: if 1 cube costs 6,500 rubles, then an element with a volume of 0.03 m 3 will cost only 195 rubles. Armed with this knowledge, you can go to the store.

Unedged materials

Boards and beams of this type have untreated side edges, since these are the first layers removed from the tree trunk. Therefore, the width parameter cannot be determined uniquely. How, then, can you calculate how many boards are in a cube?

Let's take for example a sample that has different widths on both ends: 20 cm on one side and 30 on the other. In such a situation, the average value of the indicators is taken, in our case - 25 cm. Next, the volume of such a board is determined using an already known formula.

When there is a need to purchase a large number of elements, they are stacked in such a way that all sizes match as much as possible (the difference is no more than 10 cm). Next, using simple measurements, determine the length, height of the stack, the width of the middle part, multiply them by a coefficient that takes into account the air gap: 0.07...0.09 (a larger gap - a smaller coefficient). This way they will find out how many boards are in 1 cube of unedged lumber.

The main dimensions of such boards are: 25, 40, 50 mm in height and 6000 mm in length. Other parameters are rarely set, mainly by personal order. This is due to the low demand for products and the specifics of their application. These are purchased for construction scaffolding, roof sheathing, installation of various floorings, as well as for firewood. Long boards that can be trimmed as needed are suitable for these purposes.

Pay attention to the little things

To buy wooden products and not overpay to an unscrupulous seller, use the formulas provided and independently calculate the required number of boards. A simple example: you received the actual volume of 1 element 0.035 m 3. Suppose 1 cube costs 6,000 rubles, then the board will cost 210 rubles. But if the seller rounds thousandths to hundredths, it comes out to 0.04 m 3, then you will have to pay 240 rubles for the product. Maybe for one board the difference is not so significant, but often lumber is bought in large quantities, then the difference in price can cost several hundred rubles. It is advisable to know for sure how many boards are in a cube.

Making the calculations easier

In order not to determine the volume of products individually each time, you can use ready-made data. Manufacturers have calculated how many boards are in a cube: a table compiled from the measurement results helps determine required amount material. Such reference books contain information on different types products, they are grouped according to main sizes. There are separate reports for boards, beams, platbands, baseboards and others that exist today; they are actively used not only by ordinary people, but by design engineers and builders.

Now let's look at how many boards are in 1 cube. The table is compiled for edged products.

As you can see, the reference book provides the exact number of boards in a cube. The table takes into account fractions up to thousandths, which are important to take into account when purchasing and other calculations.

Non-standard

Carefully processed products are not always used for construction and household purposes. Sometimes it is advisable to purchase unedged material, the volume of which is difficult to calculate due to the specific uneven structure of the product. There is also a solution for these cases - ready-made reference reports, from which you can find out how many boards are in 1 cube. The table for them is compiled according to the main average sizes.

The tabular data is for reference only and may differ slightly from the actual data: as already mentioned, products may differ in size by a couple of centimeters in length, for example. Therefore, each time you should pay attention to specific parameters.

It doesn’t matter what kind of lumber is needed for construction. You must be able to independently determine the required volume using formulas, a calculator and tables. This will help you avoid purchasing excess boards and significantly save your budget.

The high cost makes us think about their rational use. has always been one of the most expensive. If you actively use it, then it is advisable to find out in advance how many boards are in the cube. A table with reference data will allow you to determine the required value. You can use the board cubic meter calculator, which allows you to change the geometric parameters of other products online, or you can calculate the cubic meter yourself. We invite you to familiarize yourself with the most popular types of materials and the features of their calculation.

planed timber

Planed block

Form cross section may be different. Manufacturers offer bars with a square, rectangular or other cross-sectional shape. Requirements have been established for the aspect ratio of the finished product. Their width cannot be twice the thickness. The last linear dimension can reach 100 mm.

Planed products subjected to special processing have a smooth surface. They are widely used in the construction of various appearance which have increased demands. Actively used in industry.

Edged block

Unlike planed edged timber, it does not undergo additional finishing processing. This significantly reduces its cost. Widely used in the construction and installation of structures intended for installation facing material.

Edged board

The thickness of such lumber can reach 100 mm, and the transverse dimensions in this case should be at least twice as large. During the production process, wood is processed from all sides. As a result, it is possible to ensure the necessary geometric accuracy and relative evenness of the surface.

Edged material is used when performing work various types. Especially popular is the inch board, the size of which is numerically equal to 1 inch (25 mm). This thickness is in demand when constructing sheathing, floors and many other surfaces.

How to calculate a cube? It is enough to multiply the linear parameters to find the volume of one product. Then divide one cube by the resulting value. This will allow you to find out how many products will be in a cubic meter. Knowing the required number of products and how many of them are in a cube, it is easy to calculate the order volume.

edged board

Floor board

Designed specifically for the device. It has a width of 85÷140 mm and a thickness of 27÷45 mm. The choice of linear parameters of the product is made taking into account the subsequent operational load. Online calculator boards in a cube will allow you to calculate how much material you need to purchase for the device flooring a certain area.

floorboard

Unedged materials

Unlike edged material, such lumber has a lower cost, since its surface has partially sawn or unsawed edges (wane). Because of this, it is most often used in the manufacture or construction of rough surfaces.

How many boards are in a cube: table with standard sizes

Knowing how much is required square meters How many boards there will be in a cube depends on the linear dimensions of the selected material. Using special reference books (cubes), you can find the required quantity from the tables without tedious calculations.

How many boards are in a cubic meter: the table will allow you to find out without calculation

Reference tables contain information data for lumber of various lengths. Before you find out from the table how many boards are in a cubic meter, you should check all the linear parameters, and not just the width and thickness.

The most popular are reference tables for boards with 4 or 6. So, if we talk about how many edged boards measuring 25 by 100 mm will be in a cube, you should definitely check the length. Four-meter ones - 100 pieces, six-meter ones - 66 (66.6). Based on this, it is determined how many cubes of lumber are required.

Advice! If reference tables are difficult to find, use a calculator cubic meters, which will help you perform the necessary calculations in a fraction of seconds.

Having determined the quantity from the table, it is worth finding out how much a cube of the board weighs. To do this, you need to know the moisture content of the material. To find the answer to the question, you need to multiply the density by the volume, expressed in cubes. The basic procedure for calculating the number of boards per cubic meter

Before moving on to basic calculations and learning how to calculate a cube, you should pay attention to the unit of measurement. For wood, the unit of volume is the cubic meter. Often cubic meters, cubic meters or cubic meters are used as a symbol.

Attention! One cubic meter is numerically equal to the volume of a cube whose edges are 1 meter long.

V = L × h × b , Where

• V – the required volume of the cube, m³;
• L – product length, m;
• h – height/thickness of the material, m;
• b – width, m.

Attention! All linear parameters must be expressed in meters. If dimensions are given in millimeters, to convert to meters each original value should be multiplied by 0.001.

With the same number of square meters, how many products there will be in a cubic meter will depend on the selected thickness. If the height of the material used is large, then according to the calculations in the cube, a smaller value will be obtained. By reducing the thickness of the board, you can increase the number of products purchased.

When determining how many boards are required, it is necessary to take into account the degree of processing of the material, the grade and type of wood that was used for production. For edged and unedged lumber, the calculation will be slightly different. The calculation should be adjusted to take into account the usable area.

When calculating how much trimming material is needed, you should:

• Determine the linear dimensions of one board;
• Find the volume of one product;
• Divide 1 (cube) by the volume of one board to understand how much will be in one cube. According to calculations, the result may not be an integer value.

To find out how much unedged board is needed, you need to take measurements at several points. After this, the desired linear size is averaged, and the found value is subsequently used when performing calculations.

If there are a lot of boards and their linear dimensions differ, when starting calculations, sort by length and width. It is desirable that the linear parameters differ by a maximum of 10 cm. Then the height and length of the formed stack are measured. The height is measured in the middle. The obtained result is multiplied by a correction factor, the numerical value of which is 0.07÷0.09 units. Its meaning can be found in the cubature reference book.

Board cubic capacity calculator

If you need to do a calculation, the board cube calculator below will help you find the value you're looking for in seconds.

Good day! We bring to your attention an article that should definitely help you in determining how many board cubes to build, for example, wooden bath, need to order. In the article we will give a difficult final result for boards of a certain size, but we will also tell you what the percentage of your overpayment is for one cube of such a board, and we will show an example of independently calculating the number of boards in a cube.

What is a cube and volume

Let's start with the fact that boards are measured in cubic meters (abbr. cube). Cubic meter is the product of three quantities: the first of them is length, the second is width, and the third is height. In the case of a figure such as a “cube”, the value of the “volume” value will be equal to the length of the edge to the power of “3”. Another definition of cubic meter:

“Cubic meter (m³, cubic meter) is a unit of volume; equal to the volume of a cube with edges 1 meter long"

How to find the volume of a cube is shown in the video below (video in English):

Let's return to your future boards, namely their size. The size of the board is indicated as follows: 25x150x6000. The first number is the height (thickness), the second number is the width, and the third number is the length. The length of the board is usually either 4 meters or 6 meters.

Important! In fact, the length of the board will be greater than its nominal size. For example, a board 4 meters long actually has 4.1, or even 4.2 meters, and a board 6 meters long will have up to 6.25. As for the first two values, width and thickness (height), they must exactly correspond to the given parameter.

Calculation example for a board 25x150x6000

Let's consider the above board size 25x150x6000. The dimensions here are indicated in mm, but to determine cubic capacity, you need another unit of measurement - meter. Let's convert mm to meters and get a board 0.025x0.15x6.0. Let's apply the volume formula V= L* h* b, Where L- length, h- height, b- width. L=6.0; h=0.025; b=0.15. Thus, 6.0*0.025*0.15 = 0.0225 cubic meters. What does this mean? And this means one thing: if you know the price for 1 cubic meter of such a board, then freely determine the price of one board. Let’s say if the price of a cubic meter is 100 rubles, then for one board you will have to pay 100 * 0.0225 = 2.25 rubles.

Attention! Often, board sellers, one might say, “take advantage” of their clients by rounding up the volume of boards. For example, instead of 0.025 cubic meters, the size is indicated as 0.023. Of course, this is an insignificant deviation if you purchase less than 1 cubic meter of boards costing 100 rubles, but when a cubic meter costs, for example, 300 rubles, and you need 10 cubic meters, the overpayment will be significant.

That is why you should learn to independently determine the cubic capacity of the board. So, we were able to determine the volume of one board. But how to determine how many unedged boards are included in 1 cubic meter with dimensions of 25x150x6000. And it’s even easier to do this by using the formula:

1 cubic meter / (L*h*b) = N pieces.

We substitute the available data and get the number of boards 25x150x6000 in 1 cubic meter:

1 / (6.0*0.025*0.15) = 1 / 0.0225 = 44.4 pcs.

Important! When ordering one cubic meter 25x150x6000, you actually take 44 boards, and simply overpay for 0.4. Thus, 1% of the cost of a cubic meter is your overpayment.

Calculation of the volume and number of boards for different sizes

Below, together with you, we will determine the volume of one board and the number of boards for different sizes.

25x150x4000 (length - 4000, height - 25, width -150)

First, let's determine the volume of one such board. We apply the formula and get 4*0.025*0.15=0.015 cubic meters. meters.

Now we determine the number of boards 25x150x4000 per cubic meter: 1 / 0.015 = 66.7 pcs. As a result, 1 cubic meter of 25x150x4000 boards contains 66 pieces.

40x150x4000 (length - 4000, height - 40, width - 150)

Let's determine the volume of one such board: 4*0.04*0.15=0.024 cubic meters. meters.

And the number of boards will be calculated as follows: 1 / 0.024 = 41.6 pcs. In fact - 41 boards.

20x100x6000 (length - 6000, height - 20, width - 100)

Let's start by determining the volume of one such board, size 20x100x6000. 6*0.02*0.1=0.012.

Number of boards in 1 cubic meter: 1 / 0.012 = 83.3 pieces. We get 83 boards.

25x100x6000 (length - 6000, height - 25, width - 100)

We calculate the volume of one board using the formula: 6 * 0.025 * 0.1 = 0.015 cubic meters. meters.

If you were careful, then a board measuring 25x150x4000 has exactly the same volume, and based on this we can immediately calculate the number of boards in 1 cubic meter: 66 pieces.

40x100x6000 (length - 6000, height - 40, width - 100)

We calculate the volume of one board 40x100x6000. We substitute the parameters into the formula and we have: 6 * 0.04 * 0.1 = 0.024 cubic meters. meters.

The number of boards will be 1 / 0.024 = 41.6. Thus, paying for 1 cubic meter 40x100x6000 you will receive 41 boards.

50x100x6000 (length - 6000, height - 50, width - 100)

First, let's determine the volume of one such board. We apply the formula and get 6*0.05*0.1=0.03 cubic meters. meters.

Now we determine the number of boards 50x100x6000 per cubic meter: 1 / 0.03 = 33.3. As a result, 1 cubic meter of 50x100x6000 board contains 33 pieces.

25x150x6000 (length - 6000, height - 25, width - 150)

Let's determine the volume of one such board: 6*0.025*0.15=0.0225 cubic meters. meters.

And the number of boards will be calculated as follows: 1 / 0.0225 = 44.4 pcs. In fact - 44 boards.

30x150x6000 (length - 6000, height - 30, width - 150)

Let's start by determining the volume of one such board, size 30x150x6000. 6*0.03*0.15=0.027.

Number of boards in 1 cubic meter: 1 / 0.027 = 37.04 pieces. We get 37 boards. Perhaps, it is for a cubic meter of such a board that you will have to overpay the smallest percentage.

40x150x6000 (length - 6000, height - 40, width - 150)

We calculate the volume of one board using the formula: 6 * 0.04 * 0.15 = 0.036 cubic meters. meters.

So what is the number of boards 40x150x6000 in 1 cubic meter? It is equal to 1 / 0.036 = 27.8 cubic meters. meters. Attention! As you can see, if you round the number of such boards down, you will overpay a decent amount of money, almost 3%!

50x150x6000 (length - 6000, height - 50, width - 150)

We calculate the volume of one board 50x150x6000. We substitute the parameters into the formula and we have: 6 * 0.05 * 0.15 = 0.045 cubic meters. meters.

The number of boards will be 1 / 0.045 = 22.2. Thus, paying for 1 cubic meter 50x150x6000 you will receive 22 boards.

25x200x6000 (length - 6000, height - 25, width - 200)

The volume of one board 25x200x6000 is 0.03 cubic meters. meters. The number of boards 25x200x6000 in 1 cubic meter is 33.3 pieces.

40x200x6000 (length - 6000, height - 40, width - 200)

The volume of such a board is 6 * 0.04 * 0.2 = 0.048 cubic meters. meters. And the number of boards 40x200x6000 in one cube is 20.8 pieces.

IMPORTANT: when rounding down, the overpayment will be significant!

50x200x6000 (length - 6000, height - 50, width - 200)

The last size we will consider in this article. We calculate the volume of one such board: 6 * 0.05 * 0.2 = 0.06 cubic meters. meters. The number of such boards in 1 cubic meter will be equal to 1 / 0.06 = 16.7, which means a large overpayment when rounded towards 16 pieces!

To help you avoid confusion, below is a table with the results obtained:
