3D shapes have three dimensions - length, width and depth.
Properties of 3D shapes
3D shapes have faces (sides), edges and vertices (corners).
Faces
A face is a flat or curved surface on a 3D shape. For example a cube has six faces, a cylinder has three and a sphere has just one.
Edges
An edge is where two faces meet. For example a cube has 12 edges, a cylinder has two and a sphere has none.
Vertices
A vertex is a corner where edges meet. The plural is vertices. For example a cube has eight vertices, a cone has one vertex and a sphere has none.
