Hey user!
your answer is here..
we know about EULER'S FORMULA, it is a formula used to verify a polyhedron or to calculate the number of faces, vertices or edges.
Euler's formula = F + V - E = 2
given :-
faces = 28, verticies = 50 and edge = ?
we know that F + V - E = 2
therefore 28 + 40 - E = 2
==> 68 - E = 2
==> - E = 2 - 68
==> - E = - 66
==> E = 66
hence, the number of edges of the polyhedron is 66.
cheers!!
