Exercise 17 Page 632

Use the formula for the volume of a rectangular prism.

10ft

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= 7, w= 8, h=u, and V= 560, so we have enough information to find the value of missing dimension u.

V=l wh

SubstituteValues

Substitute values

560=( 7)( 8)(u)

▼

Solve for u

Multiply

560= 56 u

.LHS /56.=.RHS /56.

10 = u

Rearrange equation

u=10

The height u of the prism is 10ft.
