To lift an object weighing 21,000 N, how much force is needed on a

piston with an area of 0.060 m2
if the platform being lifted has an area of 3.0 m2
?

If the weight is 21,000 N which is also a force and to find Buoyancy force then 3.0 m2 + .06 m2 = 3.6 m2 21,000/3.6

Im pretty sure im doing it wrong but I really don't get this
