Pascal's law states that liquid exerts pressure equally in all directions.
Depth of water (h) = 6m
Density of water (d) = 1000 kg/m3
Acceleration due to gravity(g) =9.8 m/sec2
Pressure of water (P) =?
P= h x d x g
= 6 x 1000 x 9.8
= 58800 Pa
Hence, the water pressure exerted at the bottem of the tank is 58800 Pascal.
