Buoyant force problem

[Twilit_Truth]

It's me again. This time I actually understand the material, I just need help with figuring this one out.


The tallest iceberg ever measured stood 167 m above the water. Suppose that both the top and bottom of this iceberg were flat and the thickness of the submerged part was estimated to be 1.50 km. Calculate the density of the ice. The density of sea water equals 1.025E7 kg/m^3.


Thank you for your time.

What are you initial thoughts so far? How much water does the iceberg displace when it sinks 1.5km? What kind of volumes do we care about? What about the cross section of the iceberg, can that help at all?

This problem doesn't really have do much to do with bouyancy, only in principle, more so density and algebra if that helps at all.
