I think it's the people that can't solve the Rubik's cube that think he is smart for being able to do it.
You don't have to be smart to solve it.
But, of course the boy is smart, look at the math he was answering.
Well, the same goes for the math he was answering. There are methods for calculating mentally very quickly. Since most of us do not know the methods, we could look at someone calculating quickly and think they are smarter than they really are (relating this to people who consider those who can solve a cube to be highly intelligent)
For example, here's a trick
They asked him 85 x 85 85 square simply take the 10's digit "8" add one to get 9 and multiply the original to get:
9 x 8 = 72 now add in 25 = 7225
You could do this for all the 10's... 45 x 45 -> 4 x 5 = 20 now add in the 25 hence 2025...there are a lot of other methods like this as well. Now if he's working out more advanced mathematical problems is a different story.
