Here is the problem which I am struggling on, please help me!
Problem: A log-raft was made by lashing some logs together, where each log has a diameter 0.45 m and length 3.80 m. How many logs should be there in the raft to have 10 men safely afloat on the raft in sea water (the average mass of a man is 48 kg). Density of the logs is 800 kg/m3 and that of sea water is 1024 kg/m3.
Please show the work for the calculation so I can understand what I'm doing. Thanks!
