As any single cube is incapable of having all the digits for the 1s place.   So we are left with 3 faces on each of the cube. In which we can accomodate 3, 4, 5 and 6, 7, 8.   Still, we cannot accomodate 9. However, can we use 6 as 9 also?? If yes, my answer is correct.

So you should be able to answer the question     Quote: can we use 6 as 9 also??   yourself. IP Logged "Pi goes on and on and on ... And e is just as cursed. I wonder: Which is larger When their digits are reversed?

Generally, these things are not called "real" solutions.
