As Na is a count of the number of (atoms/molecules) in a mole of a substance, the shape of the mole seems (to me, at least) to be irrelevant. You can have a mole that is a "flat pancake", or a mole that is a cube, or a mole that is a sphere - doesn't matter - as long as you have a mole. So the "perfect cube" requirement ("Third, the value chosen..." above) seems (again, to me) "bogus", and should be discarded??

About once a month at Sigma Xi headquarters, we liven up the lunch hour with an American Scientist Pizza Lunch talk. In these informal lectures, scientists describe new research to nonscientists. The series is light on jargon but heavy on solid science. Each Pizza Lunch offers an in-depth look at its subject, whether it's bedbugs or the smart grid.

JSTOR, the online academic archive, now contains complete back issues of American Scientist from its inception in 1913 (as Sigma Xi Quarterly) through 2005.
The table of contents for each issue is freely available to all users; those with institutional access can read each complete issue.
