Which of the following cannot to be true for a polyhedron ?
Correct option is D. V = 4, F = 6, E = 6
The correct answer is option $$(d)$$.
Euler's Formula for any polyhedron$$ = F + V -E = 2$$
Where, F = Faces and V = Vertices and $$E =$$ Edges
Option $$A:$$
$$F+V-E=4+4-6=2$$
Option $$B:$$
$$F+V-E=6+8-12=2$$
Option $$C:$$
$$F+V-E=10+12-20=2$$
Option $$D:$$
$$F+V-E=4+6-6=4\neq2$$
