Best ResponseYou've already chosen the best response.0Figure out what f v and e are. I think f is faces and v is verticies

Best ResponseYou've already chosen the best response.0f is number of faces, v is vertices, e is edges

Best ResponseYou've already chosen the best response.0That would be faces + vertices = edges + 2 faces = 7, (those are flat surfaces) edges = 15 (those are like the edge of a table) 7 + v = 15 + 2 7 + 10 = 15 + 2 Vertices = 10
