The correct order of the packing efficiency in different types of unit cells is ……… .
A
fcc< bcc < simple cubic
B
fcc> bcc > simple cubic
C
fcc< bcc > simple cubic
D
bcc<fcc> simple cubic
Answer
fcc> bcc > simple cubic
Explanation
Solution
Packing efficiency of ccp or fcc = 74%
Packing efficiency of bcc = 68%
Packing efficiency so simple cubic = 52.4%
Thus, the correct order of the packing efficiency is Fcc > bcc > simples cubic
