Determine the total force acting on a $3\mathrm{.}5$ m high retaining wall per unit length of the wall. The soil that is backfilled level behind the wall is a granular soil with a total unit weight of $18\mathrm{.}6$ kN$/$m$3$ and a saturated unit weight of $19\mathrm{.}3$ kN$/$m$3.$ The active earth pressure coefficient for the soil is $0\mathrm{.}37.$ The water table is expected to raise to a depth of $2\mathrm{.}6$ below the ground surface. A surcharge of $116$ kPa is applied above the soil surface. Report your answer in terms of kN as a whole number.
