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 discussions of 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 ...
