Question

F+V-E = 2 is used for​

Answer 1

Answer: F+V-E=2 is Euler's Formula. It is used to find whether the faces, vertices, edges of a polyhedron are correct or not.It can also be used to find the number of F, V or E with any twos.

For example suppose if we take 6 Vertices 8 Edges and 6 Faces

Step-by-step explanation:

Euler's Formula=  F+V-E=2

                           =6+6-8=2

                          =12-8=2

                           =4≠2

Hence,a polyhedron can not have 6 faces, 8 edges and 6 vertices.
