Your question is all screwed up. As lexei says, it is the thickness divided by the size of the atom, But look at your numbers; you give length, width and height: which one do you call the thickness? The volume and dimensions seem totally contradictory. You say it has a volume of 5.625 mL and a mass of 0.76 g. I don't think aluminum floats. Check, correct and resubmit.
