Year 6 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.Sort each solid by whether any part of its net is curved.

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

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

  2. 2.The net of a square-based pyramid has four triangles and one square. How many faces will the pyramid have?

  3. 3.A net is made of two circles and one rectangle. Which solid does it fold into?

    • a) Cylinder
    • b) Sphere
    • c) Cone
    • d) Cube

  4. 4.How many squares are there in the net of a cube?

    • a) 5
    • b) 4
    • c) 6
    • d) 8

  5. 5.A net has six rectangles and not one of them is a square. Write the name of the solid it folds into.

  6. 6.Match each solid to what its net is made of.

    • Cube
    • Cylinder
    • Cone
    • Square-based pyramid
    • Triangular prism
    • 6 squares
    • 2 circles and 1 rectangle
    • 1 square and 4 triangles
    • 2 triangles and 3 rectangles
    • 1 circle and 1 curved piece

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

  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.
