The number of atoms in a cubic based unit cell having one atom on each

1.	The number of atoms in a cubic based unit cell having one atom on each corner and two atoms on each body diagonal isA. 8B. 6C. 4D. 9
Answer» Correct Answer - D There are four body diagonals. Atoms on the body diagonals are not shared by any other unit cell . Contribution by atoms on corners `=8xx(1)/(8)=1` and contribution by atoms on body `"diagonal"=2xx4=8,8+1=9`.
