A raft is made using several logs with 22 cm diameter and 2.2 m long, as shown in the figure. It is desired that a maximum 87 percent volume of each log will be submerged when carrying two boys weighing 440 N each. Determine the minimum number of logs that must be used. The specific gravity of the wood is 0.78.
