For a certain soil the cohesion c is $50$ kN$/$m$2,$ the unit weight is $19\mathrm{.}2$ kN$/$m$3$ and the coefficientsare Nc $=8,$ Nq $=3,$ and Ng $=2.$ Considering shear failure only, calculate the safe total load on afooting $6$m long by $1\mathrm{.}25$m wide, depth $4\mathrm{.}5$m$,$ using a load factor of $2\mathrm{.}5.$
