It is proposed to drive H-piles up to a depth of 7 m at a construction site. The average surfacearea of the H-pile is 3 m2 per meter length. The soil at the site is homogeneous sand, havingan effective friction angle of 32 °. The ground water table (GWT) is at a depth of 2 m below 
the ground surface. The unit weights of the soil above and below the GWT are 16 kN/m3 and19 respectively. Assume the earth pressure coefficient, K= 1.0, and the angle of wall friction,  
The total axial frictional resistance (in kN, up to one decimal place) mobilized on the pile against the driving is________
