hmm mabey it wasent 475, w/e my calculator gave me i put down, dont remember the exact number then.

the cub is definatly 4, 6 faces on 6 sides that arent shared, plus 2 on every edge that isent shared, plus the 8 corners is 60, since there are 64 total cubes and 60 on the outside then there are 4 in the middle

Here's a tip:
whenever the f(of anything) = x, then you know the f(x) = f^-1(x) (f inverse) - something like that...im bad at explaining things
