Exercise 18 Page 632

Use the formula for the volume of a rectangular prism.

15yd

Practice makes perfect

The volume of a rectangular prism with length l, width w, and height h can be calculated using the formula below. V=l wh We have been given that l= 12, w= 15, h=v, and V= 2700, so we have enough information to find the value of missing dimension v.

V=l wh

SubstituteValues

Substitute values

2700=( 12)( 15)(v)

▼

Solve for u

Multiply

2700= 180 v

.LHS /180.=.RHS /180.

15 = v

Rearrange equation

v=15

The height v of the prism is 15yd.
