Exercise 5 Page 34

Remember the formulas for the volume of a prism.

64 cubic feet

Practice makes perfect

We want to find the volume of the prism. Let's see consider the given prism.

Notice that our solids is square prism. We can recall that 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 square prism, the base is a square. The area of a rectangle, and also the area of the square, is the square of the side length s. We can use this to rewrite the formula. V= Bh ⇒ V= s^2(h) We know from the diagram s is 4 feet and h is also 4 feet. We can use this information to calculate the value of V.
V=s^2(h)
SubstituteValues

Substitute values

V= 4^2( 4)
CalcPow

Calculate power

V=16(4)
Multiply

Multiply

V=64
The volume of the prism is 64 cubic feet.
