1) I- section is said to be stronger because Moment of
inertia is greater than that of the rectangular cross section.
2) Ship float if the mass of the body is less than the mass
of the fluid displaced by the body when it is immersed into
it. Its based on Newton's third law. Normally Ship floats
due to Buoyance force. According to Newtons III Law,
Buoyance force will be equal to the mass of the body.
