Hydrostatic Force & It's Location on a Plate

[SheCanBuild]

Please explain how I calc the hydrostatic force and it's location on the plate.


Above the drawing is says:
A 10m equlateral plate under water
Assume 60 degrees F

I clicked on 'Manage Attatchments' to upload the drawing. Give me a minute to do it another way if it won't show up.
Thanks,
RonelleNote: I couldn't use AutoCAD to draw it because it wouldn't show up on the boards, so I had to use a paint program so please excuse the unaligned flubs and stuff...I doubt my 50 degree is 50 degrees either
