If you had a rubik's cube with 10 little squares on each side, and peeled off the outer layer, how many little cubes would you end up with?
Accepted Solution
A:
There is 6 sides in a cube, multiplying we get the number of squares: 6*10 = 60 little squares. Peeling off one layer means subtracting 10 squares from the above numbers like this: 60 - 10 = 50.
