- Calculate how much of a glacier is below the exterior of the ocean, given that the density of ice is 917 kg/m^3 and salt water has density 1025 kg/m^3.When it comes to protecting coastlines from erosion, rocks are sometimes used as a barrier. In order for a rock to not be shifted by waves, it must weigh 1,000 kilograms (approximately 1 ton). How big (what volume) does the rock need to be? You are using basalt, which has a typical density of 3200 kg/m3.21.Calculate absolute pressure at an ocean depth of 2.4 km. Assume that the density of Water, Pwater is 1.025 x 10^3 kg / m^3 and the atmospheric pressure, Patmosphere = 1.01 10^5 Pa.
