Properties of Solids

GCSE(F),

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
Cube6128All edges are the same length
Cuboid6128All corners are right angles
Cylinder320No vertices, as two edges do not meet
Sphere100No edges and no vertices
Cone210No vertices, as it only has one edge
Triangular Prism596
Hexagonal Prism81812
Square-based Pyramid585The bottom of the pyramid is a square
Tetrahedron464All edges are the same length

Examples

1. Name a shape that has only three faces.

Answer: Cylinder

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

2. What is the difference between cube and a cuboid?

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

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