Exercise 1 Page 742

Remember the formula for the volume of a prism.

4986.875 cubic inches

Practice makes perfect

We want to find the amount of water that can be contained in a rectangular kitchen sink. This amount of water is the volume of that sink. Let's assume that the sink is a rectangular prism. The volume of a rectangular prism with length l, width w, and depth, or height h can be calculated using the following formula. V=l wh We are given that l= 25.25 inches, w= 19.75 inches, and h= 10 inches, so we have enough information to calculate the value of V.

V=l wh

SubstituteValues

Substitute values

V= 25.25( 19.75)( 10)

Multiply

V=4986.875

There are 4986.875 cubic inches of water that we can contain in the sink.
