    Identify the board foot of a 2”x2”x10’ (150)?

    • A.

      6000

    • B.

      5000

    • C.

      500

    • D.

      600

    Correct Answer
    C. 500
    Explanation
    The board foot of a piece of lumber is calculated by multiplying the thickness (in inches), width (in inches), and length (in feet) and then dividing the result by 12. In this case, the thickness is 2 inches, the width is 2 inches, and the length is 10 feet. So, the calculation would be (2 x 2 x 10) / 12 = 3.33 board feet. Therefore, the answer of 500 is incorrect.
