calculate the freeboard of a 10m thick iceberg in saltwater (seawater density of 1025 kg/ m^3)

The distance frm the waterline to the top depends upon the shape of the iceberg. Perhaps you are refering to a planar ice floe with a uniform thickness. If so, the question should have been worded that way
To answer the question, you will also need to know the density of the ice in the floe. 
I think the density of the iceberg is 900 kg/m^3. So how would I set up the problem to solve it?

The answer is worked out here:

They use an iceberg debnsity of 917 kg/m^3 It can vary from iceberg to iceberg, since there are some air pockets and bubbles inside. 
thank you so much drwls
