Hello Mathgroup :
I need some help with the following. I am trying to illustrate
the concept of triple integrals, so I want to generate a 3-Dimensional
grid of n x n x n (empty) boxes at first, and then, if the center point
of a box is inside the region of integration,then show those boxes filled
(using Cuboid[]).
I spent about 6 hours yesterday trying just to generate the grid, without
success. I can generate the points of the grid with Table[].
Given that table I was able to generate the lines in the x direction for all 
the y and z values, but failed misserably to get the rest of the lines.
I am pretty sure that I can do it inefficiently with a bunch of Do's
but I am looking for an efficient way to accomplish this.
If anybody would take the time to think about this, I will be 
very grateful.
Thanks, Sergio Terrazas
