In this lesson you will learn how to find the volume of a rectangular prism with fractional edge lengths by filling it with fractional unit cubes.Slide3

In order to find the volume of a rectangular prism, you find how many unit cubes can fit inside of it.Slide4

Any whole can be broken up into fractional parts.Slide5

After changing unit cubes into fractional unit cubes, it is often forgotten to multiply by the fraction you used to divide up the original cube.Slide6

Let’s find the volume of the rectangular prism.

Draw a rectangular prism with the dimensions of 4

units x 3 units x 5 units.

Find the volume by dividing up all unit cubes into halves. Then find the volume by dividing all unit cubes into fourths. Is the volume the same? Why?

Slide11

Find the volume of a rectangular prism with the dimensions 7
