    11995200 N/m²

    Explanation:

    Pressure: The is the ratio of force to the surface area in contact. The S. I unit of pressure is N/m².

    Generally pressure in fluid can be expressed as

    P = ρgh ... Equation 1

    Where P = maximum pressure on the submarine hull, ρ = Density of ocean, h = depth of ocean, g = acceleration due to gravity.

    Given: h = 1200 m, ρ = 1020 kg/m³

    Constant: g = 9.8 m/s²

    Substitute into equation 1

    P = 1200 (1020) (9.8)

    P = 11995200 N/m²

    Hence the maximum pressure on the submarine hull = 11995200 N/m²
