(i) A straight level road is to be constructed on a hill with a uniform slope if 9H: 1V, the side slopes being 1H: 1V and 2H: 1V in cut and fill respectively and the formation width is 10 m. Calculate the total volume of earthwork in a length of 200 m, 1. When the areas of cut and fill in each cross section are equal 2. When the total earthwork in each cross section is the minimum. Also calculate the volume of cut in excess of the fill in the latter case.
