There are eight main 3D shapes that you need to learn. 3D shapes also have their own parts that can be labelled such as faces, edges and vertices.

Here are a list of 3D shapes you need to know.

Cube

Cuboid

Sphere

Cylinder

Square-based pyramid

Triangular-based pyramid (also known as a tetrahedron)

Cone

Triangular prism

There are three important terms to know when dealing with 3D shapes.

Face

A flat (2D) surface on the 3D shape

Edge

A line where two faces meet

Vertex

A point where two or more edges meet

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

By drawing a transparent cube, it can be seen that a cube has:
