Question

A right rectangular prism has a length of 2 1/2 feet, a width of 3 feet, and a height of 1 1/2

feet. Unit cubes with side lengths of 1/2 foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?

Answer 1

Answer: 11.25 ft³

Explanation:

We can use the volume formula to solve. I will turn the halves into 0.5 for calculation purposes.

V = L * W * H

V = 2.5 * 3 * 1.5

V = 11.25 ft³

The volume of the rectangular prism is 11.25 ft³.
