Grade 6 Math — 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.

123456
  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 folds up into a cuboid. How many rectangles does the net have?

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

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

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

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

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

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

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

  6. 6.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.

  7. 7.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
    • 1 circle and 1 curved piece
    • 1 square and 4 triangles
    • 2 circles and 1 rectangle

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

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

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

Answer key — Grade 6 Math — Nets of solids

  1. 1. 6
  2. 2. d) Square-based pyramid
  3. 3. b) 6
  4. 4. b) Cone
  5. 5. 3
  6. 6. 2 — Third in the row
  7. 7. Cube → 6 squares; Cylinder → 2 circles and 1 rectangle; Cone → 1 circle and 1 curved piece; Square-based pyramid → 1 square and 4 triangles; Triangular prism → 2 triangles and 3 rectangles
  8. 8. Cube → Net is all straight-sided; Cylinder → Net has a curved piece; Cuboid → Net is all straight-sided; Cone → Net has a curved piece; Triangular prism → Net is all straight-sided; Square-based pyramid → Net is all straight-sided
