# How many lumber in the cube. Tables in quantities and calculation formula

Meters are linear, square and cubic. When setting up a large construction site or even a small repair, it should be clearly guided in these terms. The ability to correctly translate the amount of certain materials into linear or cubic meters will serve an excellent service in preliminary calculations of the cost of the planned repair or construction. For example, clearly understanding how many square meters in one roll of wallpaper, you can quickly calculate the number required for pasting a room or the whole apartment.

If the upcoming repair or construction is related to the use of wooden materials, it is necessary to thoroughly to study the recalculations from linear meters to cubic, since prices can be represented on the market, either per unit of material or per cubic meter. The quantity of a bar in a cube varies and depends on its section. The easiest way to find out how many boards are in a cube is a table, but if it is not there you have to remember formulas.

## What is a cubic meter

A cubic meter (abbreviated m³) is a unit of volume and is equal to the volume of a cube with an edge length of 1 meter. In accordance with GOST 8486-86, wooden materials should have measurable cross-section dimensions and lengths, making it possible to easily calculate the number of boards included in the material cube.

To determine the dimensions of the section, it is necessary to retreat from the beam end to a distance of at least 10 cm and measure the width and height of the beam. Multiplying these values ​​on each other, we get the cross-sectional area of ​​the beam, multiplying which by the length we get the volume of one beam. By calculating the number of bars in one cubic meter, you can easily navigate between the cost of one beam and one cube of beams.

## Calculation of lumber for construction before they are purchased

How to calculate the cost of the upcoming construction? How much do the walls weigh and how powerful is the foundation needed for the future construction? All this can be calculated at the stage of choosing the size of the house or bath from a tree.

Of course, the easiest way to come to the developer is to explain what you want to see in the final version and agree on the proposed project. But, if you yourself understand the calculations of the required amount of lumber, then at the stage of discussing the cost of materials and work on the construction of the house, you can find out how real prices are offered by the construction company.

Many developers calculate the required amount of material in cubes, some consider it individually, taking the running dimensions of length - 6 or 12 m as the standard.

## The procedure for calculating the number of beams in a cube

Despite the same the principle of calculation, there are certain nuances in determining the cubic capacity and the number of different lumber.

### 1. Basic formulas for calculating the number of bars in a cube

To determine how many boards are in a cube, with bars of a certain section, you need to know three measurable parameters: length, width, and height. First, it is necessary to calculate the volume of one beam using the formula V = a * b * l (here V is volume, m³; a is height, m; b is width, m; l is length, m)

How many pieces of a bar in a cube are determined by the formula:

Where, A - the number of beams in a cube, pcs. ;

1 - one cubic meter, m³;

V is the volume of one beam, m³.

### 2. How to determine how many pieces are in a cube 100x150

In the price lists of construction companies, for convenience, indicate the section of the timber, that is, its width and height, for example, 100x150. Where 100 is the width specified in millimeters and 150 is the height. The length most often is 6 meters, or 6000 mm.

The volume of timber 100x150x6000 will be 0.09 m³.

V = 0.1 m * 0.15 m * 6 m = 0.09 m³. Here 0.1 is the width, m; 0.15 - height, m; 6 - bar length, m.

In this case, how much material will fit in one cubic meter can be found by dividing a cubic meter by the volume of one bar:

Where, 1 - one cubic meter, m³;

0.09 - the calculated volume of one beam is 100x150x6000, m³.

So you can easily calculate how many pieces of timber in the purchased volume of material by multiplying the number of pieces by the number of cubes . For simplicity and speed of counting, you can use the table: how many bars in a cube is a table of 6 meters.

### 3. How many edged boards in 1 cube

A similar situation in the calculation of the number of edged boards in 1 cubic meter of wood. For example, the board used has the following parameters 100x25x6000 (width, height, length).

The volume of one board will be 0.015 m³.

V = 0.1 m * 0.025 m * 6 m = 0.015 m³

Number in 1 cubic:

That is, a cubic meter contains at least 66 boards. When buying a cube of a cut board 100x25x6000, 67 pieces should be obtained, rounding goes upwards. For example, if you buy three cubes, you should get at least 201 pieces, and with six purchases, 401 should turn out.

### 4. How many in 1 cube of a grooved floorboard

The tongue-and-groove floor board for a better installation has a spike along the entire length on one side. When calculating the volume of one board, its length, height and net width are taken into account, that is, the width without the protruding spike. For example, the size of the board reflected in the figure below is 28x90 mm.

With a board length of 6 meters, its volume will be:

V = 0 , 09 m * 0.028 m * 6 m = 0.01512 m³

Number in 1 cubic:

### 5. How many wooden boards in 1 cube

By design, the wall paneling is vaguely reminiscent of a tongue-and-groove board floor. It also has a groove-thorn joint, ventilation slots, but the front side of the wall panel may have bevels, roundings, and even a convex surface, imitating a bar.

For the calculation, the “pure” width is used, that is, the size without the spike, the height taken as the maximum value in the board section.

The most common size of lining is 100x14. With a board length of 6 meters, the number of lining in one cube will be at least 119 pieces:

The volume of one board:

V = 0.1 m * 0.014 m * 6 m = 0.0084 m³

Number in 1 cube:

## What else to consider when calculating lumber

One of the nuances in the production of lumber is their technological length, that is, the claimed six-meter board in practice turns out to be 5-10 cm longer. the calculation of running meters of the board is not taken into account. The seller in no case has the right to add them to the total length of the board.

When buying a bar of a certain cross-section, it is important to measure the parameters during acceptance or loading, since the slightest deviation of even 1 cm leads to huge losses, especially with large volumes of purchases.

In addition to volume, it is important to remember about the weight of the purchased material, which depends on the density of the material and humidity.

## Tables for quick calculation of bar volume

Cheat sheets are presented below to quickly find out how many bars are in a cube - the table contains not only quantitative values ​​of units of material in a cubic meter, but also volumetric values ​​of bars of different sections. For example, it will show how many boards in a cube a table is - 6 meters or 3 meters in length will be a board or a bar.

When transporting materials, it is important to know not only the length of a unit of product, but also the total weight of the cargo being transported, since the load-carrying capacity of a car is limited by its design features.

## Features of lumber storage

For building a wood house, it is important to properly store the material so that its humidity is within 12%, if the humidity is higher, then the building will shrink slower below.

Here are a few rules to remember when storing lumber:

1. The storage location should be level and dry.

2. To prevent moisture from entering the surface on the platform under the first layer of material, pallets can be laid, which can be replaced by trimming boards or sleepers.

3. The distance between single items should be kept within at least 2 cm for better air circulation.

4. After 1-2 rows across the length, the crossbars are put, which can be all the same trim boards.

5. If it is not possible to build a shed above the storage area to prevent precipitation from falling, the stacks are covered with a film, excluding wrapping the ends, so as not to create a greenhouse effect inside.

## Conclusion

Knowledge of the rules for calculating the required volume of building materials will help save time and money, or simply make sure that the developer is honest. Therefore, if there are no skills to quickly convert one value to another, then when discussing the required number of building materials, you should keep at least a cheat sheet with you in the form of a cubic table.
