The pressure exerted by a static fluid depends only on the (i) depth of the fluid(h) , (ii) density of the fluid(ρ) and (iii)acceleration due to gravity(g) .
Now for a static fluid in a column with height (h) the force exerted by the fluid per unit area is due to the weight of the fluid and the expression is given by Pstatic fluid=Weight of the fluid/area=mg/A=ρVg/A=ρhAg/A=ρgh.
Therefore the fluid pressure at a given depth does not depend on the total mass or the total volume of the fluid .
