data tree management in numbering a meshed cube

Hi,

I have built a cube (10x10x10) starting from a small cubic element, which I multiplied vertically 10 times (z axis of cube). Once I had the column multiplied it 10 times to the x axis, and then the whole "surface" 10 times along y axis. 

I expected that the numbering of the cubes would follow the creation, but no. So, I want element number 1 to be the initial cube, number 10 the last element of the column, 11 the 1st element of the second column, 100 the last element of the last front column etc....

Any ideas??

Thanks in advance
