Explanation:
We know that,
Pressure (P) = Force (F) /Area(A) [ General formula of Pressure ]
= (m × g) / A [ Force = mass(m) * acceleration due to gravity(g) ]
= (d × v × g) / A [ mass(m) = density(d) * volume(v) from the formula: d=m/v ]
= (d × A × h × g) / A [ volume(v) = Base area (A) * height(h) ]
= d × h × g [ Area on the numerator and denominator get canceled out ]
= hdg [ Rewriting the above expression ]
Therefore, P = hdg #proved
