A square footing will support a column load $($P$)$ of $100$ kips and have a width $($B$)$ of $5\mathrm{.}5ft.$ The footing

depth $($D$)$ is $3\mathrm{.}5$ feet, and the footing thickness $($T$)$ is $2ft.$ The unit weight of the soil is $125pcf$ and the unit

weight of concrete is $145pcf.$ Groundwater is located $7ft$ below the base of the footing. Find the gross and
