Suppose an iceberg has a quantity of gravel frozen throughout its interior, and is floating in the ocean. (Ross) What fraction "f" of the solid volume is above the surface of the ocean? Parameters: mass of ice = 7500 kg; mass of gravel = 320 kg; density of ice = 931 kg/m³; density of gravel = 2500 kg/m³; density of sea water = 1030 kg/m³.
