An object with a density of 761.0 kg/m3 and a mass of 1399.0 kg is thrown into the ocean. Find the volume that sticks out of the water. (use ?seawater = 1024 kg/m3)
From Archimedes Principle, weight of water displaced by floating
object is equal to weight of object.
volume of water displaced = part below water line
= 1399x9.8 m/s^2/1024 x 9.8 m/s^2
= 1.366 m^3
Volume of Whole object = Mass/Density
= 1399/761 = 1.83837 m^3
Volume above waterline = 1.83837 m^3 - 1.366 m^3 = 0.47237 m^3 =
0.472 m^3 (nearly)
