1. The problem statement, all variables and given/known data 35m^3 of a boat's volume is submerged under water. What does the boat weigh? The boat is 14 metres long. 2. Relevant equations pVg=mg 3. The attempt at a solution pVg=mg pV=m m=pV=1000*35 This is what my teacher said, but I don't understand it. The submerged volume of the boat is equal to the volume of the displaced water. So by calculating m we are getting the water's mass, which is not equal to the boats mass. or is it?
