This is not really a Sage question, rather a mathematical question. What you are drawing is the unit ball of the L1 norm, which is an ocatagon. If you want to obtain a cube, you should rather draw the unit ball of the L-infinity norm. This norm does not sum the absolute values of the coordinates, but it takes their maximum.
Note that the maximum for symbolic expression, is max_symbolic
