Question

Find the number of vertices of a polyhedron having 18 edges and 8 faces.​

Answer 1

Required Answer:-

Euler's Theorem for polyhedra: F + V - 2 = E where F = # of faces V = # of vertices E = # of edges ==> V = E + 2 - F = 18 + 2 - 8 = 12 vertices

hope it helps uhh

Answer 2

12 is the vertices....of
