How to count volume in mathematics year 6

Hello,

Are you asking to explain what the meaning of volume is?

If so, volume is the measure of 3D space inside an object.

Imagine counting the number of blocks that would fit inside a larger object.

Imagine the amount of air that would fill up a balloon.

Imagine the amount of water that would fill up a swimming pool.

These are all examples of volume.

Good luck,

MrEQ
