Do you remember the formula of volume?

80 in^3

Practice makes perfect

We are given the following rectangular prism, and we want to find its volume.

The volume of a rectangular prism with l length, w width, and h height can be calculated using the formula below. V=l wh We have been given that l= 8 inches, w= 5 inches, and h= 2 inches, so we have enough information to calculate the value of V.

V=l wh

SubstituteValues

Substitute values

V=( 8)( 5)( 2)

Multiply

V=80

The volume of the prism is 80 in^3.
