Mass and volume are two units used to measure objects. Mass is the amount of matter an object contains, while volume is how much space it takes up.

Example: A bowling ball and a basketball are about the same volume as each other, but the bowling ball has much more mass.

To be precise when using measurement terms, make sure you know the difference between mass and weight.
