3d figures

  1. Aug 17, 2006 #1
    By 3d figure I mean what a pyramid with a triangular base is to a triangle and what a cube is to a square. My question is, is it possible to form a tridemensional figure with any polygon? If so, what is the relation between the number of sides of the polygon and the number of faces of the figure?

    This can only be done with the triangle, square, and pentagon. They are called the platonic solids
