a water tank has a rectangle base of dimension 3m x 2m and vertical sides. when the water level in the tank is 2m above the base caculate.

Density x Height = pressure on base
Pressure at bottom of largest side is the same as the pressure on the base.
Pressure at the top of the water level ( 2 meters) is zero.
The pressure varies linearly from zero to the base pressure over a height of 2 meters. Which gives you a right triangle 2 meters tall by base pressure wide. The center of mass of a right triangle is 1/3 the height or 2/3 meter.
Force = Pressure x area
Should be able to work it from there.
