In the cube you'll notice this gives 8  12 + 6 = 2. This relationship was discovered by the Swiss mathematician Leonhard Euler (pronounced Oiler) in the 18th century. So when you have a question like yours then you know #faces = 2  # vertices + #edges, i.e., in your case, #faces = 2 +4 = 6, so you have the cube. Penny
