Worksheet Overview

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

 

Definitions:

Face: In a 3D shape, a face 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 also be called a point. The plural of vertex is vertices.

 

Example:

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

 

A cube

 

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

 

Faces: We can immediately see 3 faces, but we have to remember that there are 3 on the back that we can't see. So that makes 6 faces altogether.

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.

 

Now let's move on to some questions.
