## Wood Density Formula

The following formula is used to calculate the Wood Density.

Dwood = m / (pi*wr^2*wl)

- Where Dwood is the Wood Density (lbs/ft^3)
- wr is the wood radius (ft)
- wl is the wood length (ft)
- m is the mass of the wood (lbs)

## How to Calculate Wood Density?

The following example problems outline how to calculate Wood Density.

**Example Problem #1**

- First, determine the wood radius (ft).
- The wood radius (ft) is given as 3.

- Next, determine the wood length (ft).
- The wood length (ft) is calculated as: 20.

- Next, determine the mass of the wood (lbs).
- The mass of the wood (lbs) is found to be: 1000.

- Finally, calculate the Wood Density using the formula above:

Dwood = m / (pi*wr^2*wl)

Inserting the values from above yields:

Dwood = 1000 / (pi*3^2*20) = 1.7683 (lbs/ft^3)

**Example Problem #2**

The variables needed for this problem are provided below:

wood radius (ft) = 6

wood length (ft) = 30

mass of the wood (lbs) = 1500

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

Dwood = m / (pi*wr^2*wl) =** **(lbs/ft^3)
