question

A barge of mass 15,000 kg, made from metal of density 7500 kg\bulletm^-3, is being loaded in a closed dock of sur-face area 6633 m^2 with ore of density 3 g\bulletcm^-3. When 80,000 kg of ore are aboard, the barge sinks. How does the water level in the dock alter? The area of the barge is assumed negligible in comparison with the area of the dock.
