Acrab fisherman has built a crab trap out of plastic pipe and wire mesh. the overall mass and volume of the trap are 5.59 kg and 6,213 cm^3, respectively. to catch crab, the trap must sink to the ocean floor. the fisherman has several lead weights to add to the trap to ensure it sinks. if sea water has a density of 1,021 kg/m^3 , and each lead weight has mass of 113.4 g and volume of 10.0cm^3, what is the minimum number of weights the fisherman must add so that the trap sinks to the ocean floor?
