Answer
move upward
Reason — A hollow rectangular box standing upright has its centre of gravity somewhere near its middle so when a heavy brick is placed on top of the box, additional mass is added above the original centre of gravity of the box.
Because the heavier mass is now concentrated at a higher position, the combined centre of gravity of the box–brick system shifts upward.
Therefore, the centre of gravity moves upward.
