Calculating the volume of cubes and cuboids

Home learning focus

Learn how to calculate, estimate and compare the volume of cubes and cuboids.

This lesson includes:

  • two slideshows
  • three worksheets with answers

Created in partnership with Twinkl


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.

Volume is the amount of 3D space taken up by something.

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

Find the volume of these two shapes and then compare them. Which shape has the greater volume? Remember to use the formula length x width x height to workout the volumes.
