An iceberg has a density of 0.920 g/cm^3.

Question

Saltwater has a density of 1.025 g/cm^3. When an iceberg floats in the ocean, what percentage of the volume of the iceberg is above water, and what percentage is below water?

Answer 1

The force balance is ρ_sV_sg = ρ_wV_wg where w and s indicated water and solid. V_s is total solid volume and V_W is the volume of the solid under the water.

V_w/V_s = volume fraction under water = ρ_s/ρ_w
