explanation...

A compound formed by elements A and B crystallizes in the cubic structure where A atoms are at the corners of the cube and B atoms are at the face centres. The formula of the compound is:

A atoms are at the corners of the cube. There are 8 corners and each contributes one eight to the unit cell. Total number of A atoms =8×
