Question

Â?A class teacher writes the formula F + V-E =
2 on a black board. For which of the following
options is this formula true?​

Answer 1

Euler's polyhedron formula F + V-E = 2

Step-by-step explanation:

Euler's polyhedron formula F + V-E = 2

F = faces

V = vertices

E = edges

its not applicable for surface of convex polyhedron

Example :

                                      F        V      E       F + V-E = 2

Tetrahedron          4        4    6       2

Cube                              6         8      12      2

its not applicable for surface of  nonconvex polyhedron
