A pyramid has a base that can have any number of sides, plus triangular faces that connect each vertex of the base to a single apex point. For example, a pyramid with a square base has five faces (1 square base and 4 triangular faces), while a pyramid with a triangular base has four faces (1 triangular base and 3 triangular faces). Thus, the total number of sides varies depending on the shape of the base.
