Find the Volume of a 3D shape

In this activity, we will find the volume of cubes and cuboids.

 

You will need a calculator!

 

The volume of  a 3D shape is how much room it takes up!

 

Let's start with a cube!

 

 

The area of one side of this cube is base x height:

5 x 5 = 25 cm² 

 

To find the volume, we multiply this area by how deep it is (it is a cube, so it is 5 cm deep):

 

Volume = base x height x depth

Volume = 5 x 5 x 5 = 125 cm³

 

 

Let's do a cuboid!

 

 

The area of one side of this cuboid is base x height:

3 x 4 = 12 cm² 

 

To find the volume, we multiply this area by how deep it is (we can see from the diagram it is 5 cm deep).

 

Volume = base x height x depth

Volume = 3 x 4 x 5 = 60 cm³

 

Let's try some questions.
