Answer 1

Answer:

You have to apply Euler's law

Faces + Vertices = Edges + 2

(1) F + V = E + 2

      F + 6 = 12+2

       F +6  = 14

To find F, we have to eliminate 6. To eliminate 6, we have to add its additive inverse -6. Whatever changes we do to one side of the equation should be done on the other side too. so if we add -6 to both sides,

                         F + 6-6 = 14 - 6

                                F     = 8

No.of Faces = 8

(2) F + V = E + 2

    20 +12= 30+2

       32    = 32

Since it satisfies Euler's law, we can say a polyhedron can have 20 Faces, 12 Vertices and 30 edges.
