Question

8. A pyramid has a volume of 8 cubic feet. The height is 2 feet. The base is rectangular. Give possible dimensions for the length and width of the base.​

Answer 1

base = 12 ft²

The base could be 3 ft x 4 ft, 6 ft x 2 ft, etc. (any numbers multiplied together = 12)

Explanation:

volume = 1/3bh

8 = 1/3b(2)

multiply both sides of the equation by 3:

24 = 2b

b = 12 ft²
