1.	Percentage of free space in which cubic close packed structure and in body centred packed structure are respectively
Answer» 40% and 26% 30% and 26% 26% and 32% 32% and 48% Solution :Packing efficiency in CCP STRUCTURE=74% %free space =100 - 74 = 26% Packing efficiency in bcc structure = 68% %free space = 100 - 68 = 32%
