How many faces, edges and vertices does a cube have? A cube has six faces, 12 edges and eight vertices. Each face of a cube is an identical square, and every edge has an identical length, which is equal to the length of the sides of the faces.

Mathematicians have derived Euler's formula for these and similar shapes. It states that for a polyhedron the number of faces plus the number of vertices minus the number of edges is always two.
