How many edges does a polyhedron with 28 faces and 40 vertices have calculator?

66

Explanation:

Faces + Vertices  - Edge  = 2
28 + 40 - Edge = 2
Edge = 28 + 40 - 2
Edge = 66

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!!
