a polyhedron has 36 edges and 21 faces, how many vertices does it have?
thank you
Those of ya'll lookin for the answers of Connexus...
Unit 6:Lesson 1 Polyhedrons practice

You can use Euler's polyhedral formula:
V+F-E = 2
V=number of vertices
F=number of faces
E=number of edges
Substitute
E=36 and F=21 into the polyhedral formula and solve for V.
