A square pile group of 9 piles passes through a recently filled up material of 3.5 m depth. The diameter of the pile is 30 cm and placed at spacing of 0.8 m centre to centre. The unconfined compressive strength of the material is 60 kN/m² and the unit weight of recently filled up material is 16 kN/m³. The negative skin friction (in kN, rounded off to one decimal place) would be.
