Types of 3D shapes

Take a look at these common 3D shapes and their properties:

 

Sphere

Balls are shaped like a sphere.

Properties:

  • 1 curved face
  • No vertices
  • No edges

 

Cube

Dice and sugar cubes are shaped like cubes.

Properties:

  • 6 faces (all shaped like squares)
  • 12 edges
  • 8 vertices

 

Cuboid

Fridges and wardrobes are usually shaped like cuboids.

Properties:

  • 6 faces (all rectangular, or a mixture of rectangles and squares)
  • 12 edges
  • 8 vertices

 

Square-based pyramid

The pyramids in Egypt look like square-based pyramids. They are called square-based pyramids because the face on the bottom is a square.

Properties:

  • 5 faces (1 square and 4 triangular)
  • 8 edges
  • 5 vertices

 

Cone

Ice cream cones, traffic cones and birthday hats are shaped like cones.

Properties:

  • 2 faces (1 circular at the base and 1 curved)
  • 1 edge around the base
  • 1 vertex

 

Cylinder

These look like tubes and toilet rolls.

Properties:

  • 3 faces (2 circular and 1 curved)
  • 2 edges
  • 0 vertices

 

Tetrahedron

A tetrahedron can also be called a triangular-based pyramid.

Properties:

  • 4 faces (all triangular)
  • 6 edges
  • 4 vertices

 

Triangular prism

Door stops and tents are examples of triangular prisms.

Properties:

  • 5 faces (2 triangular and 4 rectangular)
  • 9 edges
  • 6 vertices
