3D shapes are also known as solids because they occupy space meaning they can be handled in real life. There are eight main 3D shapes which all have different properties.

Identifying 3D shapes

There are eight common 3D shapes that you need to learn.

Properties of 3D shapes

3D shapes can characterised by three main properties: faces, edges and vertices.

Property

Definition

Face

A flat (2D) surface which is part of the 3D shape

Edge

A line where two faces meet

Vertex

This is a corner, a point where two or more edges meet.

Example 1

How many faces, edges and vertices does a cube have?

Draw a transparent cube to show its properties.

Count the number of faces, edges and vertices.

There are $\underline{6}$ faces. These faces meet to create $\underline{12}$ edges. These edges meet to create $\underline{8}$ vertices.

Note: It may be useful to know how to draw each 3D shape.
