HEY MATE ⭐⭐⭐
HERE'S THE ANSWER ✌
____________
Body-centered cubic unit cell (B.C.C): A unit cell contains one constituent particle present at the centre of each face, along with eight particles at its corners.
No of atoms present in this unit cell = (8 x 1/8) + 1 = 2
(Each Corner atom contributes 1/8th portion to the unit cell)
( Body centered atom is 1).
