A certain life raft has a rigid cylindrical shape with a height of 0.712 m and a radius of 2.738 m. This is shown in the diagram below. What total mass (raft material plus people) would the life raft have, if one third of its height is submerged below still sea water of density 1025 kg/m3? Please enter your answer in kilograms and take the Earth's gravitational field strength to be g=9.8 N/kg. Also, write it in scientific notation that is correct to exactly 3 significant figures (such as 3.43*10^3, for instance)
