A.For a proposed new road, the cross-sectional areas at different sections are as
follows:
Calculate the volume enclosed between chainage 1000 m and 1120 m by the
prismoidal and end area formulae.
B. A vertical sided rectangular tank ABCD is to be constructed such that sides AB and
AD have lengths 60 m and 30 m, respective ly. The formation level is to change
uniformly from 82 m above datum along AD to 80 m above datum along BC.
Readings were taken with a level in the following order:
Estimate the amount of excavation required in the construction of the tank.
