Looking at hexagonal closest packing, face centred (or closest packing) and body-centered packing.(adsbygoogle = window.adsbygoogle || []).push({});

So I need to know abit about each.

I would think body-centered was the least efficient having looked at the arrangment. The main layer has to be centered a certain way to fit the rest..which means that he spheres are not close to each other but it looks more organized. Hexagonal looks the most packed to me.

I also need to know..in terms of volume how do thetwo more efficient ways of packing compare..and also what is the relationship between coordination number, packing and density (as mass/volume)?

Thanks
