Paint the cube!
For first side we can choose colors in 6 ways. For second, 5, and so on. So we can paint the cube in 6! ways.
However, it has 8 corners. Any three colors, painted on three faces meeting in a corner, can be reproduced on any of these.
Also, around a corner, we can rotate the a color combo three times and rotate the cube back, to get the same view of the cube.
Hence the number of distinct cubes will be
6!/(8*3)
