The fluid force on a submerged surface can be calculated using the formula: Force = ρghA, where ρ is the density of the fluid (in this case, water, which is approximately 62.4 lb/ft³), g is the acceleration due to gravity (which is generally factored into the density value for these types of problems and thus not separately listed), h is the depth of the fluid above the surface (6 feet), and A is the area of the surface (10 square feet). Plugging in the values: Force = 62.4 lb/ft³ * 6 ft * 10 ft² = 3,744 lb.
