Year 5 Maths — Nets of solids

Say which solid a net folds into, and which flat shapes a solid's net is made from.

Name: ________________________

Before you start

Here is a cube opened out flat. Find out which face of the finished cube each flat square folds up to become.

1. The top
2. The left-hand face
3. The front
4. The right-hand face
5. The back
6. The bottom

The front stays where it is and the other five fold up around it. Six squares and six faces, each appearing exactly once — a net with a square missing or a square repeated folds into nothing at all.

1.Match each solid to what its net is made of.
- Cube
- Cylinder
- Cone
- Square-based pyramid
- Triangular prism
- 6 squares
- 2 triangles and 3 rectangles
- 2 circles and 1 rectangle
- 1 square and 4 triangles
- 1 circle and 1 curved piece
2.A net has six rectangles and not one of them is a square. Write the name of the solid it folds into.
3.A net is made of two circles and one rectangle. Which solid does it fold into?
- a) Sphere
- b) Cylinder
- c) Cone
- d) Cube
4.A net is made of one circle and one curved piece. Which solid does it fold into?
- a) Cylinder
- b) Triangular prism
- c) Cuboid
- d) Cone
5.A cylinder is unfolded into its net. Write the name of the flat shape that appears twice in it.
6.The net of a square-based pyramid has four triangles and one square. How many faces will the pyramid have?
7.A net is made of one square and four triangles. Which solid does it fold into?
- a) Cylinder
- b) Square-based pyramid
- c) Cube
- d) Triangular prism
8.A net folds up into a cuboid. How many rectangles does the net have?
