How many cubic units is this rectangle?

What did you find?

Yes, it is 8 cubic units!

How about this one?

Remember… there are some cubes you can’t

see!Watch..

.

Now Count Them

What did you find?

Yes! There are 12 cubic units!

What’s the formula?

The formula for finding the volume of a rectangle is ….

L x W x H = VolumeL x W x H = Volume

This means we take the This means we take the lengthlength times the times the width,width,

then multiply that by the then multiply that by the heightheight..

Let’s try it!

L = 3

H = 3

W = 2

3 x 3 x 2 = 18 cubic units

Find the volume of this one!

What did you

find?

4 x 2 x 3 = 24 cubic units
