# Learn

In today's lesson, you will learn to calculate the volume of cubes and cuboids. To do so, we'll need to use the correct unit of measurement for finding the volume of fixed of a fixed object, called **cubic units**.

So today, we'll be using **cubic centimetres (cm³) ** and **cubic metres (m³)** to measure the the volume of the cubes and cuboids. Find out more in the slideshows below.

You'll need something to jot down your answers as you work through the slideshows.

Now we know how to work out the volume of a cuboid, the next slideshow will explain how to calculate and **compare** the volume of cuboids.

Remember that:

- < means
**less than**. - > means
**greater than**
