**Steve**, Wednesday, March 14, 2012 at 5:33pmdiagonal of a square is √(s^2+s^2) = s√2

diagonal of a cube is √(s^2+s^2+s^2) = s√3

Think of it as the hypotenuse of a triangle perpendicular to the base, where one leg is the base diagonal (s√2) and the height is s, making the hypotenuse

h^2 = 2s^2 + s^2 = 3s^2
