### VOLUME

What is Volume?
• Volume is the measure of the capacity of a container.
• It is the measure of how much a container of a particular shape will hold - liquids, dry substances, etc.
Cubic Units
• Volume is measured in cubic units.
• Use cubes to fill a rectangular prism such as a box.

1 unit(length)

1 unit(height)

1 unit(width)

One Cubic Unit

A unit might be measured in inches, feet, centimeters, etc.

How many cubic units is this rectangle?

What did you find?

Yes, it is 8 cubic units!

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 = Volume

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

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

NOTES!
