Exercise 20 Page 660

Remember the formula for the volume of a prism.

18 inches

Practice makes perfect

We will by using the formula for volume of the prism to calculate the length l of the prism. Let's see the given measurements on the rectangular prism.

The volume of a rectangular prism with length l, width w, and height h can be calculated using the following formula. V=l wh We have been given that V= 720, h= 10, and w= 4, so we have enough information to calculate the value of the length l.

V=l wh
720=l( 4)( 10)
720=l(40)
18=l
l = 18

The length l of the prism is 18 in.
