And when they say "calculate the weight under water," the question is vague: "weight" could mean "the force due to gravity," which will still be the same, or "weight" could mean "apparant weight" which would be the force due to gravity minus the buoyant force.

For the first part- you do know what density means, do you not?

For the second part- how much water is displaced?(The density of water is [itex]1g/cm^3[/itex]

Do you have a textbook? Are you allowed to read it?
