1.	In which pair most efficient packing is present?A. Hcp and bccB. hcp and ccpC. bcc and ccpD. bcc and simple cubic cell
Answer» Correct Answer - B packing efficiency is the percentage to total filled spaces by partices and it can be calculated as packing efficeency `("Volume occupied by spheres in the unit cell ")/("total volume of unit cell ")xx100` since packing efficiency for hcp or ccp is calculated to be 74 % which is maximum among all type of crystals.
