A cubic centimetre is volume that is made by a cube that is 1 centimetre on each edge.

A cubic metre is volume that is made by a cube that is 1 metre on each edge.

A cube number is the product of three repeated whole numbers.

Explain how to calculate the volume of a cuboid and a cube

Maths

In this unit pupils will explain what volume is using a range of contexts and describe the units used to measure volume. They will explain how to calculate the volume of a cuboid and explain what a cube number is. In the future unit pupils will explain the use of the commutative and distributive laws when multiplying three or more numbers. 

In the prior unit pupils calculated the area of a rectangle using multiplication and used their knowledge of area to solve problems. In this unit pupils will explain what volume is using a range of contexts and describe the units used to measure volume. They will explain how to calculate the volume of a cuboid.

Understand the concept of volume

Tick all of the shapes which are cuboids.

There are 3 rows of 6 cubes in a layer. There are 2 layers.

There are 3 rows of 6 cubes in a layer. There is 1 layer.

There are 3 rows of 6 cubes in a layer. There are 6 layers.

How can you describe the number of cubes in this cuboid?

Complete the expression which would calculate the volume of this shape.  3 × 3 × {{ }}

Which of these expressions give the volume of this shape?

What is the volume of this shape? {{ }} cm$$^3$

What might you measure in cubic centimetres?

Each cube in the image above is one cubic centimetre. What is the volume of this shape? {{ }} cm$$^3$$
