For a convex polyhedron, F, V and E count faces, vertices and edges. Which is Euler's relation?

AF + V + E = 2
BF + E − V = 2
CF − V − E = 2
DF + V − E = 2
Answer & Solution
Correct answer: D. F + V − E = 2
Euler's relation for a closed convex polyhedron is the number of faces plus vertices minus edges equals two.
