338 - What is the difference between mass and volume?

Imagine you have a big box of Styrofoam peanuts and a small rock.

The 'volume' is the amount of space something takes up. Both the big box and the small rock can take up a certain amount of space, but the box is bigger.

The 'mass' is how heavy something is. Even though the box is bigger, the small rock is heavier because it's denser. The box is light because it's made of airy Styrofoam peanuts.
