9.04 3D shapes

Lesson

Are you ready?

Being able to identify the key features of shapes can help us in this lesson. 

How many edges does each shape have?

Learn

This video looks at prisms, it starts with showing how a prism is made by looking at its net, and then looks at the faces, edges and vertices of a prism.

Question 1

Here is a rectangular prism.

  1. There are $\editable{}$ faces.

  2. There are $\editable{}$ vertices.

  3. There are $\editable{}$ edges.

Question 2

Here is a square pyramid:

  1. How many faces does it have?

  2. How many vertices does it have?

  3. How many edges does it have?

 

Learn

This video looks at cones, spheres and cylinders.  All these shapes have curved faces.  Let's see how we can tell which one is which.

Question 3

Here is a cone.

  1. How many faces does it have?

  2. How many vertices does it have?

  3. How many edges does it have?

 

Remember!

Cones, spheres and cylinders all have curved faces.
