A rowboat measures 4ft wide by 10ft long. How much (in inches) will the boat sink into the water when two 200 lbs me get into the boat?

A: I am having a hard time getting the volume of the boat…does anyone have a suggestion?

This was my plan:

W boat= volume * density of a wood

W men= 400lb = 181.57kg * p.8 N/kg= 1779.39N

F bouy= W water = mg=pVg= 1000kg/m^3 * volume displaced *9.8 N/kg =

F lift = F buoy – W boat – W men =

I don’t even know if I am headed in the right direction…..Can anyone help?

Thank for the help in advance.
