A cubic unit cell has one atom on each corner and one atom on each bod

1.	A cubic unit cell has one atom on each corner and one atom on each body diagonal. The number of atoms in the unit cell is
Answer» SOLUTION :CONTRIBUTION by atoms on the corners = `8times1/8=1`. As atoms on the body diagonals not shared by any other unit CELL and there are four body diagonals, their contribution = 4 `therefore "total atoms in the unit cell " = 5`
