On a lake, a boat with a length of 3 metres and a width of 2 metres is floating. When a guy climbs on board, the boat sinks by 1 cm. The man's bulk consists of:
A. 12 kg B. 60 kg C. 72 kg D. 96 kg
Explanation: Volume of water displaced = 0.06 m3 (3 x 2 x 0.01) m3.The mass of a man is equal to the volume of water displaced multiplied by the density of water, which is (0.06 x 1000) kg = 60 kg.
