A vertical door in a dam is triangular in shape, with its base parallel to the surface of the liquid (y 9554 N/m³) situated 8.00 m below the surface and 6.00 m wide. The point of the door is above the base, 5.00 m below the surface of the liquid. Determine the force due to liquid pressure acting on the door. The force is kN (express answer rounded to the nearest kN)
