Question

A right rectangular prism has a square base with side lengths of 5 inches and a height of 9 inches. What is the volume of the right rectangular prism?

A.
90 cubic inches
B.
225 cubic inches
C.
19 cubic inches
D.
45 cubic inches

Answer 1

B. 225 cubic inches

Explanation:

The volume is the product of the base area and the height:

V = Bh

The area of the square base is the product of the side lengths:

B = (5 in)^2 = 25 in^2

For a height of 9 in, the volume is ...

V = (25 in^2)(9 in) = 225 in^3

The volume of the right rectangular prism is 225 cubic inches.
