How many board feet are in a 2 x 4 x 12 piece of lumber?

To calculate the board feet in a piece of lumber, you can use the formula:

[

\text{Board Feet} = \left( \frac{\text{Thickness (in inches)} \times \text{Width (in inches)} \times \text{Length (in feet)}}{12} \right)

]

For a piece of lumber that is 2 inches thick, 4 inches wide, and 12 feet long, you first need to substitute the dimensions into the formula.

1. Convert the dimensions:

• Thickness = 2 inches

• Width = 4 inches

• Length = 12 feet

2. Plug these values into the board feet formula:

[

\text{Board Feet} = \left( \frac{2 \times 4 \times 12}{12} \right)

]

3. Simplifying the equation:

[

\text{Board Feet} = \left( \frac{96}{12} \right) = 8

]

Thus, there are 8 board feet in a 2 x 4 x 12 piece of lumber. This calculation is straightforward and shows how to arrive at the number
