EULER'S FORMULA- FACE+VERTICES-EDGE=2
1) LET THE FACE BE; X
     GIVEN, X+6-12=2
                   X-6=2
                   X=6+2
                   X=8

2) LET THE VERTICE BE-X
   GIVEN, 5+X-9=2
                 X-4=2
                 X=2+4
                 X=6

3) LET THE EDGE BE-X
   GIVEN,20+12-X=2
                 32-X=2
                 X=30
