The names of 3D solid shapes should be known. The number of faces (the flat surfaces), the number of edges (where two faces meet), and the vertices (corners) should also be known.

Name | Shape | Faces | Edges | Vertices | |

Cube | 6 | 12 | 8 | All edges are the same length | |

Cuboid | 6 | 12 | 8 | All corners are right angles | |

Cylinder | 3 | 2 | 0 | No vertices, as two edges do not meet | |

Sphere | 1 | 0 | 0 | No edges and no vertices | |

Cone | 2 | 1 | 0 | No vertices, as it only has one edge | |

Triangular Prism | 5 | 9 | 6 | ||

Hexagonal Prism | 8 | 18 | 12 | ||

Square-based Pyramid | 5 | 8 | 5 | The bottom of the pyramid is a square | |

Tetrahedron | 4 | 6 | 4 | All edges are the same length | |

Frustum | 3 | 2 | 0 | A cone, with a small cone removed from the top |

Name a shape that has only three faces.

A circle at each end; and a curved surface going them.

Answer: Cylinder

What is the difference between cube and a cuboid?

The edges of a cube are all the same length; the height, width or length will vary.

Answer: The edges of a cube are all the same length; the edges of a cuboid vary in length.
