## Lumber Weight Formula

The following formula is used to calculate a lumber weight.

W = V * D * Q

- Where W is the weight (lbs)
- V is the volume (ft^3)
- D is the density (lbs/ft^3)
- Q is the number of pieces

## Lumber Weight Definition

**What is lumber weight? **A lumber weight is a measure of the total mass of a set of 1 or more pieces of lumber.

## Common Lumber Densities

**How much does lumber weigh? **Lumber weight depends on the size and density of the lumber being used. Some common densities for lumber can be found in the list below.

- Pine: 2.5 lbs/ft^3
- Walnut: 3.3 lbs/ft^3
- Cherry: 3 lbs/ft^3
- Maple: 3.75 lbs/ft^3

## Example Problem

How to calculate lumber weight?

**First, determine the density of the lumber.**For this example, we will be working with pine wood. This has a density of 2.5 lbs/ft^3.

**Next, determine the board foot of lumber.**This is also known as the volume in cubic feet. Multiply the length by the width by the height to calculate the volume. The lumber for this example has a volume of 10 ft^3.

**Next, determine the quantity of lumber.**For this example, we have 10 equal pieces.

**Finally, calculate the lumber weight.**Using the formula above: W = 2.5*10*10 = 250 lbs.
