I'm trying to solve for the ideal c/a ratio of hcp packing. why doesn't c/2 =a/2, looks like they pass through the same amoutn of radius's so I'm not sure the geometry to use. Used this pic http://www.engr.ku.edu/~rhale/ae510/lecture2/sld013.htm but it is more confusing to me how 1.67 comes out. Help please?
