Answer to Question #162646 in Physics for Kent Bulawin

Question

a raft is 2.35 m wide x 1.25m long and 0.365m deep.What is the buoyant force on the raft if only 0.125m of the raft remains above the water

Answer 1

The force is

$$F=\rho_w g V_\text{under water}=\\ =1000\cdot9.8·(2.35\cdot1.25\cdot0.125)=3600\text{ N}.$$
