Percentage of free space in cubic close packed structure and in body centred packed structure are respectively

A

40% and 26%

B

30% and 26%

C

26% and 32%

D

32% and 48%

Text Solution

Verified by Experts

The correct Answer is:
C
Packing efficiency in ccp structure=74%
%free space =100 - 74 = 26%
Packing efficiency in bcc structure = 68%
%free space = 100 - 68 = 32%
