The density of an object or a substance is its mass, divided by its volume. We use the formula: \(density = mass ÷ volume\) to calculate the density of an object or substance. For example ...

Note: We are purposely using the terms “size” and “amount” instead of “volume” in this lesson about density. We are also using “heavy”, “light”, and “weight” instead of “mass”. If your students have ...

To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The ...

The density of aluminium is 2.7 g/\(cm^3\). This means that a 1 \(cm^3\) block of aluminium has a mass of 2.7 g. If mass is measured in grams, g, and volume in cubic centimetres, \(cm^3\), the ...
