Question

To find the volume of a rectangular prism, you can use the formula of V = l w h. A rectangular prism has a volume of 60 cubic centimeters, a height of 3 cm, and a length of 5 cm. What is the width of the prism?

Answer 1

W = 4

Explanation:

The nice thing about algebra is that you can look for any variable in an equation as long as you have the number for the other variables.

1. Write our the equation. V = l w h

2. Put in as many numbers as you can. 60 = 5 w 3

3. Isolate the variable. To do that perform the mathematical opposite to the target on both sides. So to get rid of five, we have to divide it on both sides of the equal sign.

60/5 = w 3

12/3 = w

4 = w

The width is 4cm
