Question

A class teacher writes the formula f+v-e=2
on a black board. For which of the following options
in 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
