Draw a cubic unit cell (a) in projection (showing the fractional heights of the atoms) and (b) as a three-dimensional representation that has atoms at the following positions: Ti at ( 1 2 , 1 2 , 1 2 ), O at ( 1 2 , 1 2 ,0), (0, 1 2 , 1 2 ), and ( 1 2 ,0, 1 2 ), and Ba at (0,0,0). Remember that a cubic unit cell with an atom on the cell face, edge, or corner will have equivalent atoms displaced by the unit cell repeat in any direction. Of what structural type is the cell?
