a crystalline solid is made of X,Y,Z atoms. atoms X are present in ccp latice ,Y occupy all the octahedral voids & Z occupy all the tetrahedaral voids if all atoms body are diagonally removed then formula of solid will be?

CCP lattice has in total 4 atoms in which 1/8 * 8 =1 cornaer atom 
it ha 4 octahedral voids and  8 tetrahedral voids so 
the ratio of x:y:z willl be equal to 1:1:2.
but if all the diagonal atoms are removed the number of x atoms will be reduced to 3 and thus the ratio will be 3:4:8.
