8. How many cubic feet are in 3 cubic yards?

A. 27 cu. ft.
B. 5,184 cu. ft.
C. 9 cu. ft.
D. 81 cu. ft.

I picked D,because there are 27 cubic ft. in 1 yd. So you would take 27 cubic ft multiply by 3, which equals 81 cu. ft. Is that correct?

  • Math -

    The conversion is 1 yard = 3 feet.
    Thus,
    1 yd^3 = 3^3 ft^3 or 27 ft^3
    If there are 3 yards,
    3 yd^3 = 3 * 27 ft^3 = 81 ft^3

    You're correct. :)
