A square concrete pile of 10 m length is driven into a deep layer of uniform homogeneous clay. The average unconfined compressive strength of the clay, determined through laboratory tests on undisturbed samples, is 100 kPa. If the ultimate compressive load capacity of the driven pile is 632 kN, what is the required width of the pile? (Take bearing capacity factor Nc = 9 and adhesion factor α = 0.7)
