An aquarium 8 m long, 5 m wide, and 4 m deep is full of water. Find the following:

the hydrostatic pressure on the bottom of the aquarium 39200,

the hydrostatic force on the bottom of the aquarium 568000 ,

the hydrostatic force on one end of the aquarium?

i got the first 2 but i cant get the force on 1 end

the equation i got is integral from depth1 to d2of (density)(gravity)(length)x

what i tried was integral for 0 to 4 of (1000)(9.8)(4)x

but it did not work for me
