**What is volume?**

**Volume** is the total amount of 3D space that an object takes up.

**What is capacity?**

**Capacity** is the total amount of fluid that a container can hold. We use the word 'capacity' when we are measuring liquids.

In this activity, you will be asked to use formulae to calculate the volume of a shape.

We use **cubic units** **(cm³) **when calculating the volume.

To find the volume of a **cube or cuboid,** we use the formulae

**Length x height x width**

**V = L x H x W**

Example:

What is the volume of this cuboid?

V = L x H x W

V = 5 x 3 x 9

V = 15 x 9 = **135 cm³**
