Exercise 1 Page 428

Remember the formula for the volume of a prism.

64 ft^3

Practice makes perfect

Let's see the given measurements on the rectangular prism.

The volume of a prism is found by multiplying the area of the base by the height of the prism. V=Bh In the case of a rectangular prism, the base is a square. The area of a square, and also the area of the base, is the side length s squared. We can use this to rewrite the formula. V= Bh ⇒ V= s^2 h We are given that h= 4 and s= 4, so we have enough information to calculate the value of V.
V=s^2 h
V= 4^2 * 4
V=16* 4
V = 64
The volume of the prism is 64 ft^3.
