The volume of the upper and lower parts of the iceberg is V1 and V2 respectively. The known density of sea water is 1.03 × 10 cubic kilogram per cubic meter, and the density of water is 0.9 × 10 cubic kilogram per cubic meter. Try to calculate the percentage of the volume of the iceberg below the water surface in the total volume

I can't figure it out. I need to know the density of ice
Percentage = ice density / seawater density
