 # 9.04 3D shapes

Lesson

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

How many edges does each shape have?

1. 2. ## 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.

### Apply

##### Question 1

Here is a rectangular prism. 1. There are $\editable{}$ faces.

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

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

## Learn

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

### Apply

##### 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.

### Apply

##### 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.
