Summary
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.
name | illustration |
| 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.
name | Definition |
| 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:
