A road section to be laid out passes through a hilly terrain illustrated below. The section
in fill is a trapezoidal three level section while that of cut is a five level section. The
lowest point on the valley (fill) section is 16 m away from sta 2 + 040, with elevation equal
to 90.0 m and the highest point on the hill (cut) section is located 10 m from sta 2 +120,
with elevation equal to 110.60 m. The width of the base of the road is 10 m with side slopes
equal to 2:1 for both cut and fill. Considering 20% shrinkage, determine the following:
a. volume of fill
