Question

A rectangular prism has a volume of 2000 cubic inches. The height of this prism was changed from 5 inches to 20 inches to create a new rectangular prism. The other dimensions stayed the same. What is the volume of the new rectangular prism? Just type the number

Answer 1

Find base area (both prism have the same base area):

Volume = base area x height

2000 = base area x 5

base area = 2000 ÷ 5 = 400 in²

Find Volume of the new prism:

Volume of the new prism = 400 x 20 = 8000 in³

Answer: 8000 in³
