7. Volumes of Rectangular Prisms

Continue to next subchapter

Exercise 9 Page 329

Remember the formula for the volume of a prism.

310 in.^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= 23, w= 35, and h= 34. Let's substitute these values into the formula for the volume of a prism!

V=l wh

SubstituteValues

Substitute values

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

Multiply fractions

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

Multiply

V=18/60

a/b=.a /6./.b /6.

V=18 ÷ 6/60 ÷ 6

Simplify quotient

V=3/10

The volume of the prism is 310 of a cubic inch.
