Watch...


Now count them
Now Count Them

What did you find?

Yes! There are 12 cubic units!


What s the formula
What’s the formula?

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

L x W x H = Volume

This means we take the length times the width, then multiply that by the height.


Let s try it
Let’s try it!

L = 3

H = 3

W = 2

3 x 3 x 2 = 18 cubic units
