As density = mass / Volume
Use formula,
Z= density Na (a)^3 divided by molecular mass
Here Z = 2 for BCC
Change density by above formula into mass / volume.
Mass will be cancelled by num. and deno.
Substitute values of Na,a and Z to calculate Volume.
Hope you get your answer.

Answer:2.81×10^-23 cm^3
Explanation: volume of unit cell =a^3
= 2.81×10^-29m^3
=2.81×10^-23 cm^3
