Hydraulic press, Hydraulic break and hydraulic lift are three examples that uses pascal's law.

Density of a substance is defined as the mass per unit volume.

The force that acts perpendicular to and into a surface is called thrust.

Pascal's law states that liquid exerts pressure equally in all directions.

Given,

Depth of water (h) = 6m

Density of water (d) = 1000 kg/m^{3}

Acceleration due to gravity(g) =9.8 m/sec^{2}

Pressure of water (P) =?

We know,

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.
