7. Volumes of Rectangular Prisms

Continue to next subchapter

Exercise 12 Page 329

Remember the formula for the volume of a prism.

1516 m^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= 58, w= 34, and h= 2. Let's substitute these values into the formula for the volume of a prism!

V=l wh

SubstituteValues

Substitute values

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

a=a/1

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

Multiply fractions

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

Multiply

V=30/32

a/b=.a /2./.b /2.

V=30 ÷ 2/32 ÷ 2

Simplify quotient

V=15/16

The volume of the prism is 1516 of a cubic meter.
