Imagine that ice cubes are floating in a large bowl of punch. if there are enough cubes, they will cover the surface of the punch and bump into one another. parts of the cubes will be below the surface of the punch and will displace the punch. will some cubes displace more punch than others? explain your answer

Of course.  Every cube displaces as much water as WEIGHS as much as the cube weighs.  

Since the cubes with the most volume also WEIGH the most, bigger cubes displace more water, and smaller cubes displace less water.

Same goes for icebergs.  For the same reason.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
