Question
Given the following notes for three irregular sections, compute the volume of
earthwork lying between station sta. 1+200 and sta. 1+240 by (a) the average-end
area method; and (b) by the prismoidal formula. The road bed width is 20 m and the
side slopes 1.5:1. Determine the difference in volume between average-end area
method and prismoidal method in cu. meter. (Hint: the computed area in sta. 1+220 is
the Am).
