[QUOTE="TheSodesa, post: 5439941, member: 512094"] What makes you say this? Since I know that r = 0.414R, and looking at the picture the edge of the unit cube is clearly e = 2R + 2r, methinks I should be able to extract both R and r from the information given. I was able to calculate e (although my calculation could be wrong, and according to the book it is). [/QUOTE]
