What is the hight of a rectangular prism if the width is 20, the lenth is 36.8 and the volume is 1472m?

Remember that volume of a rectangular prism is: 

volume = length x width x height

Since you're given three values, you can easily figure out the missing value (which is your height).

1472 = 36.8 x 20 x h 

1472 = 736 x h 

Divide both sides by 736, and you'll get your height! 

80 x h
Or...
(40 • 2)h
