Eulers Formula

Polyhedron:

Any figure / shape whose faces are polygons that is triangles, quadrilaterals etc is called a polyhedron.

Eulers Formula:

Each polyhedron has faces, edges and Vertices. If F, E and V denote respectively the number of faces, edges and vertices of a polyhedron, then the formula showing the relation between them is the called Euler's formula. The formula is

F - E + V = 2.
