11. A hexagonal plate is submerged in a fish tank filled with water as shown below. The bottom half of the plate is trapped in pebbles such that no water reaches the lower half of the plate. Find the hydrostatic force on the top half of the plate if the water level is 8 m above the top of the plate. Show the integral used to find the force in your work, then you can use your calculator to evaluate the integral. (10 points) 10 m 5 m 5 m 16 m
