Packing fraction ion fcc, bcc and sc are 0.74, 0.68 and 0.52 respectively. So ratio =(0.74/0.74):(0.68/0.74):(0.52/0.74) =1:0.92:0.70 .

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

1 : 0.92 : 0.70

0.70 : 0.92 : 1

1 : 0.70 : 0.92

0.92 : 0.70 : 1

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

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

$= 1 : 0.92 : 0.70$ .

0.70 : 0.92 : 1

1 : 0.70 : 0.92

0.92 : 0.70 : 1

Packing fraction ion fcc, bcc and sc are 0.74, 0.68 and 0.52 respectively. So ratio =0.740.74​:0.740.68​:0.740.52​ =1:0.92:0.70 .

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

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

$= 1 : 0.92 : 0.70$ .
