1) Label all the points in the following sketch with their point coordinates You get to pick your own numbers for the points - I would however suggest some sort of logical sequence. Color coding the different types of points (e.g. atoms at corners, atoms on face centers, similar to your worksheet 1) is highly recommended. Please note that this structure is very similar to an fcc structure ( 8 atoms on corners, 6 atoms on cube faces), but does have 4 additional atoms per unit cell
