El teorema de Euler para poliedros establece una relación entre los números de caras (C), aristas (A) y vértices (V) que se cumple para todo poliedro convexo. La relación es la siguiente:
he usual definition is that every face must have the same number of edges, and the same number of faces must meet at every vertex. The key to most proofs of this classification is the Euler characteristic.
To find the best deal find the unit rate. City express unit rate for pants per dollars is 1 pair : $20.33 Denim Planet unit rate is 1 pair : $36.50 New Threads Unit rate is 1 pair : $27.50 So City Express is the best deal
