A dry sand sample was tested in direct shear and yielded a shear strength of 144 kPa under normal stress of 204 kPa. Lab results indicate the soil's wet unit weight is 18.8 kN/m3 and the saturated unit weight is 19.9 kN/m3. Determine the shear strength, in kPa, within the native sand deposit at a depth of 2.1 m below the water table. The water table is 3 m below the ground surface. Provide your answer with 2 decimal places, do not include the units, and assume a unit weight for water of 9.81 kN/m3.
