    Answer:

    4.05×10⁶ N.

    Explanation:

    The following data were obtained from the question:

    Breadth (B) = 4 m

    Length (L) = 10 m

    Standard pressure (P) = 101325 Nm¯²

    Force (F) =..?

    Next, we shall determine the area of the wall. This can be obtained as follow:

    Area (A) = length (L) × breadth (B)

    A = 10 × 4

    A = 40 m²

    Finally, we shall determine the force exerted on one side of the wall as follow:

    Standard pressure (P) = 101325 Nm¯²

    Area (A) = 40 m²

    Force (F) =.?

    Pressure (P) = Force (F) /Area (A)

    101325 = F/40

    Cross multiply

    F = 101325 × 40

    F = 4.05×10⁶ N.

    Therefore, a force of 4.05×10⁶ N was exerted on one side of the wall.
