7. Volumes of Rectangular Prisms

Continue to next subchapter

Exercise 13 Page 329

Remember the formula for the volume of a prism.

258 cm^3 or 3 18 cm^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= 1 23, w= 56, and h= 2 14. Let's substitute these values into the formula for the volume of a prism!

V=l wh

SubstituteValues

Substitute values

V= 1 23( 5/6)( 2 14)

MixedToFrac

a bc=a* c+b/c

V=1* 3+2/3(5/6)(2* 4+1/4)

Multiply

V=3+2/3(5/6)(8+1/4)
