Question

using euler formula find the number of vertices if the number of faces and edges are 10 and 12 respectively

Answer 1

HERE IS YOUR ANSWER

=we,know that

=Faces = 10

Let the vertices be = x

=edges = 12

Euler formula = FACES + VERTICES - EDGES =2 (f+v-e)=2.

10 + x - 12 =2

Transposing

x = 2-10+12

x= 4

10 + 4 - 12 = 2
