How about this one?
Remember… there are some cubes you can’t see!
Watch...

7. Yes! There are 12 cubic units!
Now Count Them
What did you find?
Yes! There are 12 cubic units!

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

9. Let’s try it!
L = 3
H = 3
W = 2
3 x 3 x 2 = 18 cubic units

10. Find the volume of this one!
What did you find?
4 x 2 x 3 = 24 cubic units
