A concrete retaining wall is shown in the figure. The fill behind the wall has a unit weight of 100pcf whose active soil pressure may be assumed equivalent to a fluid pressure of 30psf per foot. The passive soil pressure may be assumed equivalent to a fluid pressure of 300 psf per foot. The live load surcharge behind the wall is equivalent to an additional of 2ft of fill. Unit weight of concrete is 150pcf. Consider 1 ft length of wall.Which of the following most nearly gives the factor of safety against overturning?
