Remember the formula for the volume of a prism.

320 mm^3

Practice makes perfect

We will calculate the volume of the prism. Let's see the given measurements on the rectangular prism.

The volume of a rectangular prism with length l, width w, and height h can be calculated using the following formula. V=l wh We are given that l= 45, w= 12, and h= 38. Let's substitute these values into the formula for the volume of a prism!

V=l wh

SubstituteValues

Substitute values

V= 4/5( 1/2)( 3/8)

Multiply fractions

V=4* 1* 3/5* 2* 8

Multiply

V=12/80

DivFracByFracSameDenom

.a /4./.b /4.=a/b

V=12 ÷ 4/80 ÷ 4

Simplify quotient

V=3/20

The volume of the prism is 320 of a cubic millimeter.
