Class 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. 1. The top
  2. 2. The left-hand face
  3. 3. The front
  4. 4. The right-hand face
  5. 5. The back
  6. 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. 1.A net has six rectangles and not one of them is a square. Write the name of the solid it folds into.

  2. 2.The net of a triangular prism has two triangles and some rectangles. How many rectangles does it have?

  3. 3.Sort each solid by whether any part of its net is curved.

    Groups: Net is all straight-sided · Net has a curved piece

    • Square-based pyramid
    • Cube
    • Cuboid
    • Cone
    • Cylinder
    • Triangular prism

  4. 4.A net folds up into a cuboid. How many rectangles does the net have?

  5. 5.A net is made of one circle and one curved piece. Which solid does it fold into?

    • a) Triangular prism
    • b) Cone
    • c) Cylinder
    • d) Cuboid

  6. 6.A net is made of one square and four triangles. Which solid does it fold into?

    • a) Triangular prism
    • b) Cube
    • c) Cylinder
    • d) Square-based pyramid

  7. 7.A cylinder is unfolded into its net. Write the name of the flat shape that appears twice in it.

  8. 8.This net folds up into a cube. The first square in the row is marked. Tap the square that will end up opposite the marked one.

    Write the number of the part.
