Take a look at the two boxes below. Each box has the same volume. *If each ball has the same mass, which box would weigh more? Why?*

The box that has more balls has more mass per unit of volume. This property of matter is called density. The density of a material helps to distinguish it from other materials. Since mass is usually expressed in grams and volume in cubic centimeters, density is expressed in grams/cubic centimeter.

We can calculate density using the formula:

In the previous lesson you calculated the mass and volume of two blocks. If you would like to review these sections click on the appropriate links shown at the left.

Mass = 79.4 grams

Volume=29.8 cubic cm.

Mass= 25.4 grams

Volume=29.8 cubic cm.
