A metal has bcc structure and the edge length of its unit cell is

3.04\mathop \mathrm{A}\limits^ \circ

. The volume of the unit cell in

\;\mathrm{c}{\mathrm{m}^3}

will be

View answer and explanation

Correct option: B

2.81 \times {10^{ - 23}}\;\mathrm{c}{\mathrm{m}^3}

Option B (

2.81 \times {10^{ - 23}}\;\mathrm{c}{\mathrm{m}^3}

) is correct because it is the volume of the unit cell calculated from the given edge length.
