Draw the figure to illustrate your understanding of all the problems. Show complete formulas and solutions. Round off to 3 decimal places. At STA. 51+33 of a proposed road, the center height of the cross- sectional area is 1.4m in fill while the center height of the cross- sectional area at STA 51+93 2.8m in cut. The width of the proposed road is 14m with a required side slope of 2H:1V for both cut and fill. Determine the volume of cut and the volume for fill using the END-AREA Method.
