    Answer:

    P = 17658 Pa = 17.658 KPa

    Explanation:

    The pressure applied by a liquid at a given depth is given by the following formula:

    P = \rho gh\\

    where,

    P = Pressure = ?

    ρ = density = 9000 kg/m³

    g = acceleration due to gravity = 9.81 m/s²

    h = depth = 40 cm/2 = 20 cm = 0.2 m

    Therefore,

    P = (9000\ kg/m^3)(9.81\ m/s^2)(0.2\ m)\\\\

    P = 17658 Pa = 17.658 KPa
