Question

A metal has bcc structure and the edge length of its unit cell is 3.04 . The volume of the unit cell in cm3 will be

Solution

Correct option is

2.81 × 10-23 cm3

 

Volume of unit cell (V) = a3

                                      = (3.04 × 10-8)3

                                      = 2.81× 10-23 cm3
