Answer:
Pressure depends on the height of the water not on the area of the tank.
P (ressure) = density * g * h
h = 2000 nt / m^2 / (1000 kg / m^3 * 9.8 m / s^2) = .204 m
W = M V g = M h A * g
If you want the weight of the water on the entire base (A = 1000 m^2)
W = 1000 kg / m^3 * .204 m * 1000 m^2 = 2.04E5 * 9.8 m / s^2
W = 2E6
But pressure = Force / area
Force = 2000 * 1000 = 2E6
