For a cubic unit cell, the number of atoms can be calculated using the formula:

Number of atoms  = [(4 \times 1/8) + (4 \times 1/2) + 1] = 4  atoms

where the first term accounts for the atoms located at the corners, the second term accounts for the atoms located at the centre of each face, and the last term accounts for the atom located at the centre of the cube
