Understand Conversions Between Standard Units of Volume

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

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

Now, let's have a go at some questions using this information!
