 A 1.8m x 1.8m footing is located at a depth of 1 m below the ground surface in a deep deposit of compacted sand (f'=
 33 , f' = 28 , γ = 17.5 kN/m). Calculate the ultimate net bearing capacity considering several factors (e.g., shape,
 depth, and inclination) when the groundwater table is located (a) at 5 m below the footing base, (b) at the ground surface,
 (c) at the footing base, and (d) at 1.5 m below the footing base. Also, explain the effects of the groundwater levels in the
 bearing capacities of the footing with your own words. If the information is not given for the calculation, please assume it
 reasonably.
