For Questions 2a and 2b A full shipping container falls off a ship, fills with seawater, and sinks to the bottom of the harbor. The container is 6.1m long, 2.4m wide and 2.6m high. Salvage experts dive down to it and attach a spherical balloon to the container, which they can pump air into from the surface. The density of seawater is 1029 kg/m^3. The formula for volume of a sphere is V = 4/3 * pi * R^3.
