Expert Answer

Step 1

In Body Center Cubic structure, the crystal structure of metals tells about the contribution of each corner and an atom present in the center of crystal structure. All the atoms are present at the corner of the crystal structure and one atom is in the center of the BCC structure.

An unit cell is defined as the a group of atom which tells about the crystal structure of the given symmetry. 

Lattice structure can be prepared using unit cell.

Step 2

Total number of corners = 8.

All the corner contribute 1/8 per unit cell.

So, for 8 corners,

total number of unit cell = 1/8×8=1.
