Figure Q1 (c) shows the vectors of the primitive bec cell that connect atoms at thevertices of the bcc cube with an atom in the cube center and lattice constant, a Note that the volume of the bcc primitive cell is V = a1 a2 X 13). i. Write the primitive translation vectors ai, az and a3 of bcc. ii. Solve the formulation for the volume of the bcc primitive cell. (5) a az az a, Fig. Q1 (c): Body-centered cubic lattice
