Step-by-step explanation:
Given that,
The radius of a bcc unit cell is, [tex]r=2.55\times 10^{-8}\ cm[/tex]
We need to find the length of the edge in pm.
We know that,
For a bcc unit cell, the relation between the radius and the length of the edge is given by :
Edge length,
[tex]a=\dfrac{4r}{\sqrt{3} }\\\\a=\dfrac{4\times 2.55\times 10^{-8}}{\sqrt{3} }\\\\a=5.88\times 10^{-8}\ cm[/tex]
Hence, this is the required soolution.
