Volume describes the amount of space a 3D shape takes up.
In this activity, we'll be working out volume by counting the number of cubic blocks in a selection of cubes and cuboids.
A cubic block takes up 1 cubic cm. This is written as 1 cm³
Here is a cubic block.
Its volume is 1 cm³
Let's have a go!
What is the volume of this cuboid?
We know that the shape is made up of cubic cm blocks.
We simply count the number of blocks to find the volume.
There are 6 blocks.
The volume is 6 cm³
Easy, right?
Now, why don't you have a go at a few questions?
