4. Using the figures below, sketch the lattice points for the BCC and FCC unit cells: BCC FCC 5. Use the space below to list the point coordinates for ALL of the atoms that are associated with the BCC unit cell that you drew above. 6. Three crystallographic directions in a cubic system are shown below. Please label the correct crystallographic direction (e.g. [101]) next to each of the directions shown.
