A boat floating in fresh water displaces water weighing 37.3 kN. What is the difference between the volume of fresh water displaced and the volume of salt water displaced (Vfresh - Vsalt)?

F(bu) = 37.3E3 kg/m^3

(rho)fresh water = .998E3 kg/m^3?

(rho)salt water = 1.10E3 kg/m^3?

2. Relevant equations

F(bu) = m(of water displaced)g

m(of water displaced) = (rho)V

3. The attempt at a solution

F(bu) = (rho)Vg

V = F(bu)/[(rho)g]

V(f) - V(s) = [F(bu)/(rho)][1/(rhof)-1/(rhos)]

V(f) - V(s) = [37.3E3/9.8][1/(.998E3) - 1/(1.10E3)] = .354m^3

This is wrong?
