A square pile group of 16 piles penetrates through a filled-up soil of 3 m depth. The pile diameter is 250 mm and pile spacing is 0.75 m. The unit cohesion of the material is 18 kN/m2 and the unit weight of soil is 15 kN/m3. Compute the negative skin friction of the group (in kN, up to two decimal places) if the adhesion coefficient of the pile and clayey soil around is 0.4.
