Tabulate the number of faces, edges and vertices for the following polyhedrons: (Here ‘V’ stands for number of vertices, ‘F’ stands for number of faces and ‘E’ stands for number of edges).

Solid F V E F+V E+2

Cuboid

Triangular pyramid

Triangular prism

Pyramid with square base

Prism with square base

What do you infer from the last two columns? In each case, do you find
$F + V = E + 2$ , i.e., $F + V – E = 2$ ? This relationship is called Euler’s formula.
In fact this formula is true for any polyhedron.
