I'm in the process of building a fairly large fish tank,9'-0" depth and 7 feet across in a hexagon shape. It's got a cone shape at the bottom, and I plan to bury 2' or 3' in the ground so that will help support some of the weight. So obviously this thread is of interest to me. I don't meant t simplify this issue, because I know that it's physics, but wouldn't the force on the wall at the bottom be the same as the weight of the water on the floor just below it? The total water in the tank willweigh(41.5692 x 7.8333 = 325.624sq. Ft. Then 325.624 x 7.48' =) 2,435.6675 gals.

2,435.6675 x 8.34' = 20,313.4669 pounds

Then one foot up 284.0548 x 7.48' = 2,124.7299. 2,124.7299x 8.34 = 17,720.2474 pounds.
Let me know what you think. Thanks!
