Assuming that directly above point A is the water with height 0.6 meters, the pressure at point A is 5,880 Pascals, neglecting atmospheric pressure above the tank. This can be solved using the density of water, gravitational constant, and height of the water. This is because pressure is dependent on height and type of material. The calculations are as follows:
Pressure = density(gravitational constant)(height)
Pressure = 1000 kg/m^3 (9.8 m/s^2)(0.6m)
Pressure = 5,880 Pascals
