Q. The ratio of packing density in fcc, bcc and simple cubic structure is respectively,

NTA AbhyasNTA Abhyas 2020The Solid State

Solution:

Packing fraction ion fcc, bcc and sc are 0.74, 0.68 and 0.52 respectively.

So ratio $=\frac{0.74}{0.74}:\frac{0.68}{0.74}:\frac{0.52}{0.74}$

$=1:0.92:0.70$ .
