This reply may be useless for you since you got the weight brick, but it can be
useful for those who don't have any:
Brick 2x4 is not the ideal part for adding weight because it's hollow. Plates
have definitely more ABS per volume unit. 24 plates 1x1 have the same dimensions
as 1 brick 2x4, but they weigh more than double weight of it (according to
Bricklink). Nevertheless, the amount of plates 1x1 needed to counterweight the
weight brick would still occupy about 4x more volume than the weight brick.
