UNIT III
5. List various methods available for finding the areas consisting regular boundary and irregular
boundary. Define Simpson's rule and derive the equation to finding the area.
The road embankment 10m wide at formation level with side slopes 2:1 and with an average height
of 5m is constructed with an average gradient 1 in 40 from contour 220m to 280m. Calculate

ii) Volume of embankment in m3.
6. The width of a certain road at formation level is 9.50 m with side slopes 1in 1 for cut and 1 in 2
for filling. The original ground has a cross-fall of 1 in 5. If the depth of excavation at the center
line of the section is 0.4 calculate the areas of the cross-section in cut and fill.
