Transcribed Image Text:Q3) A railway embankment, 12 m wide, with side slop 1:1 is to be calculated for
its volume of earthwork. Assuming the ground to be level in a direction transverse
to be centre line, calculate the volume contained in a 180 m length the centre
heights at 30 m intervals being in meters as 0.6, 1.2, 1.8, 1.5, 1.2, 0.9, 0.6 using (a)
Prismoidal Rule, (b) Trapzoidal Rule or End area method, (c) comment on the
obtained results and (d) compute the volume upto 150 m chainage.
Q4) The areas within the underwater contour lines of a reservoir are as follows:
