Question

A box of cereal is shaped like a rectangular prism. The box is 20 centimeters long and 30 centimeters high. It's volume is 3600 cubic centimeters. Find the width of the box.

Answer 1

With a rectangular prism with a length of 20 cm, height of 30 cm, and volume of 3600 cm, first set up the formula for the volume of a rectangular prism.

V=bwh

Then, plug in your known numbers

3600=20*30*w

Simplify

3600=600w

Use inverse operations to solve for w

3600/600=6

The width is 6 cm
