how do you find the weight of displace water?
given 1m on each side of a cube that is being hold down by a string, density = 1000kg/m^3, and is 500m below the surface. Please also provide me with the formula. Also how do you find the magnitude of the buoyant force acting on the cube?

the submerged cube displaces water equal to its volume
and
D = m/V
so
m = D*V = 1000 * (1x1x1) = 1000 kg
then
Fw = m*g = 1000*9.81 = 9810 N
the weight of displaced water = buoyant force (Archimedes Principle)
