A compound formed by elements X and Y has a cubic structure in whch X atoms are at the corner of the cube and also at the face centers. Y atoms are present at the body center and at the edge center of the cube. If all the atoms are removed from one of the plane passing through the middle of the cube, calculate total number of atoms in the cube,
