What is volume?

Volume is how much space something takes up inside.

Imagine you have a big water bottle and a small juice box. The water bottle can hold more liquid than the juice box because it has a bigger volume, that means it takes up more space inside.

Think of volume like filling up a sandbox with sand. If your sandbox is big, you need more sand to fill it completely. That’s like having a bigger volume. A smaller sandbox only needs a little bit of sand, just like something with less volume takes up less space.

You see volume every day! When you pour milk into your cereal bowl, the amount of milk is its volume. If you use a tall glass, it might hold more milk than a short one, that’s because it has a bigger volume inside.

So next time you fill up a cup or stack blocks, remember: you’re working with volume, and it's just how much space something can take up!
