An underwater research habitat features a flat, rectangular escape hatch on its lower deck. The diagram shows the hatch, which has a length of 0.80 m0.80\text{ m}0.80 m and a width of 0.60 m0.60\text{ m}0.60 m.
At the habitat's operational depth, the fluid pressure acting upwards on the bottom of the hatch is 1.25×105 Pa1.25 \times 10^5\text{ Pa}1.25×105 Pa.
Calculate the total force of the water acting on the bottom of the escape hatch.
