I have a cylindrical water tank of mars, where acc. due to gravity= 3.71

The pressure at the surface of the water is 110 kPa, and the depth of the water is 14.5 m

The pressure of the air outside the tank is 91 kPa

Find the net downward force on the tanks flat bottom of area 2.4 m^2, exerted by the water and air inside the tank and the air outside the tank

2. Relevant equations

p= F/A

3. The attempt at a solution

alright, I found the downward force to be 3.93x10^5 N

upward force to be 2.18x10^5

I thought the sum of these forces would give me the net forces but I must've been mistaken because the answer was wrong.
