Question

using euler's formula, find the faces in a polyhedron, if the number of vertices and edges are 6 and 12 respectively.

Answer 1

Euler's formula:

F+V-E=2

then using euler's formula we shall know that, the faces in a polyhedron is 10 faces

so,
according to the formula

 F=10
 V=6
 E=12

THEN:

F+V-E=2
10+6-12=2
16-12    =2
        4   =2
           4-2
            =2
