Answer
An iceberg with a density of 920 kg/m3 is floating in the northern seas where the density of sea water is 1025 kg/m3. What percentage of the iceberg can be seen above the water?
Therefore, 10.2%, (100% – 89.8%) of the iceberg’s volume is above the water and can be seen. 
From the previous example problem, we saw that the percentage of floating material that is under water is equal to
denisty of floating object = Percent of object’s volume that is under water.  density of fluid is floats in
ANSWER
  920 kg/m3 = 89.8 % …under water  1025 kg/m3
