Please provide clear and detailed steps so I can compare my work

Problem 3: Hydrostatic force on a submerged surface. Consider a rectangular inclined plane fully submerged in water as shown in the figure below. The origin O is located at the intersection of the plane surface and the free surface. Assume the width of the inclined plane to be w (width w is into the page). All other relevant parameters are shown in the figure. a) (2 points) Calculate the pressure at point 1 , a distance y from the origin. b) (4 points) Determine the resultant hydrostatic force FR on the upper face of the submerged surface. What is the direction of the force? c) (2 points) Calculate the numerical value of the hydrostatic force in S.I. units when b=5cm,w=20cm and =30. Use Table 1.6 in the book (also available on Canvas) for physical properties of water
