A container is filled with mercury to a depth of 10 cm. On top of the mercury floats a 40 cm thick layer of water with a density of 1×10³ kg/m³. If the density of mercury is 13.6×10³ kg/m³, calculate the pressure at the bottom of the container.
A. Pressure = 1.0×10⁴ Pa
B. Pressure = 2.6×10⁴ Pa
C. Pressure = 5.3×10⁴ Pa
D. Pressure = 8.9×10⁴ Pa
