We know that
The atom at governor make 1 by 8 contribution while atom at body centre make one contribution to the unit cell.
Number of atom of A per unit cell= 8(corners) *1/8 = 1
Number of atoms B per unit cell= 1
formula of compound= AB
The atom at the body centre would be in contact with all the atom at the corner. the coordination number of A is 8 .Similarly, coordination of B is also 8
