Determine the total force per unit length acting on a 3.6 m high retaining wall. The soil that is backfilled level behind the wall is a granular soil with a total unit weight of 18.4 kN/m3 and a saturated unit weight of 19.5 kN/m3. The at-rest earth pressure coefficient for the soil is 0.47. The water table is expected to raise to a depth of 2.5 below the ground surface. A surcharge of 59 kPa is applied above the soil surface. Report your answer in terms of kN as a whole number.
