Question: Determine the required width ( B ) of a square footing to carry a column load of 1 2 0 0 k N , including

Determine the required width (B) of a square footing to carry a column load of 1200kN, including the weight of foundation.
The depth of footing is 500mm. A minimum factor of safety of 3 is required.
The soil below and around the footing is medium dense sand with an effective friction angle of 32 degrees and zero cohesion.
The saturated unit weight of soil is 19.8kNm3.
The ground is flat, and the base of footing is horizontal.
The applied load is vertical with 100mm eccentricity in both directions
When solving please hand write every step.
