Answer 1

Not sure how you put 9 numbers in six cubes.

If you put 9 numbers (1-9) in an array of 3x3 squares such that each row, column or diagonal adds up to 15, it is called a magic square.

There is only one distinct 3x3 magic square, meaning that all other variations can be obtained by rotation or reflexion of the others.

Here is one version:

8 1 6
3 5 7
4 9 2

If you want to know how to find the position of the numbers of a 3x3 magic square, (or a 5x5...), post a reply to that effect.
