Each face has (10*10) 100 cubes painted. However adjoining faces share 10 smaller cubes:
Face 1 has 100 unique cubes painted.
The two opposite faces adjoining face 1 have (100-10) unique cubes painted.
The two other adjoining faces have (100-10-9-9)or (8x9)unique painted cubes.
The face opposite face 1 has (8X8) unique cubes painted.
Total 100 + 2*90 + 2*72 + 64.

Three convicts are brought into the warden's office. He says he can parole one of them and to decide which one he will parole he takes out 5 hats (3 red and 2 white). He stands behind them and places a hat on each one of their heads and puts the other two remaining hats in a drawer. He tells the prisioners they can look at the others hats and if they can tell which hat they have on they will be the one who is paroled. The first man looks at the other two and says, "I don't know." The second man looks at the others hats and says, "I don't know."
