The relation between edge length and radius of an atom in a bcc structure is related as:
$r=\sqrt{3}/4\alpha$
Given,$a=4.29\times {10}^{-8}\mathrm{c}\mathrm{m}$
For bcc structure,
$r=\frac{\sqrt{3}}{4}a=\frac{\sqrt{3}}{4}\times 4.29\times {10}^{-8}\mathrm{c}\mathrm{m}$
$=1.857\times {10}^{-8}\mathrm{c}\mathrm{m}\simeq 1.86\times {10}^{-8}\mathrm{c}\mathrm{m}$
