Question

The volume for a rectangular prism is given by the formula V = l · w · h, where l is the length of the prism, w is the width of the prism, and h is the height of the prism.

If the volume of a rectangular prism with a length and width of 3 inches is 81 cubic inches, what is the height of the rectangular prism?
A.
9 inches
B.
75 inches
C.
14 inches
D.
27 inches

Answer 1

Answer: It is A, or 9 inches

Explanation:

1. We know that the length and width is 3, so that is 3 * 3, which is 9

2. Therefore, with the volume of 81, we would know that 9 * 9 is 81, so the height is 9 inches
