The volume is the amount of space occupied by a closed 3D shape.

A compound shape is a shape created using two or more basic shapes. A composite shape is an alternative for compound shape.

Problem solving with further surface area and volume

In this unit, pupils have increased their knowledge of volume which is used in the compound measures unit as the formula for density involves volume. 

In the prior unit, pupils built upon their learning of the area of different shapes. In this unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.

In this unit, pupils will further develop their understanding of shapes by considering the surface area and volume of pyramids, spheres and cones.

2D and 3D shape: surface area and volume (pyramids, spheres and cones)

The amount of space occupied by a closed 3D shape is called the {{}} of the shape.
