A rectangular storage tank is sealed and pressurized, P$,$ to $519\mathrm{.}7$ kPa $($ga$).$ It stores a liquid with a relative density of $1\mathrm{.}57$

The liquid in the tank has dimensions:

H $=14\mathrm{.}5$ m

W $=3\mathrm{.}1$ m

L $=5\mathrm{.}9$ m

What is the force acting on the Front side of the tank $($HxW side$)$ due to the hydrostatic pressure of the fluid? Answer in kN$,$ to $2$x decimal places.
