When we are dealing with 3D shapes, we have to be able to find the amount of vertices,faces and edges.

Definitions:

**Face:** A face in a 3D shape is one of the sides of a shape - it is an **area.**

**Edge: **An edge is where two faces meet - it is a **line**

**Vertex:** A vertex is the corner of a shape, it can be called a **point**. The plural of vertex is vertices

**Example.**

**Find the ****amount**** of faces, edges and vertices for a cube.**

When you are completing these questions, remember that there will be hidden bits that you can't see,

**Faces: **We can immediatly see 3 faces, but we have to remember that there are 3 on the back that we can't see.

**Edges.** There are 9 we can see and another 3 we can't - This gives 12 edges.

**Vertices:** There are 7 we can see and one hidden away at the back. This gives 8 overall
