Edges and faces
WebFor any polyhedron that does not self-intersect, the number of faces, vertices, and edges are related in a particular way. Euler's formula for polyhedra tells us that the number of vertices and faces together is exactly two more than the number of edges. Euler's formula for a polyhedron can be written as: F + V - E = 2. Here, F is the number of ...
