Earthworks At Station 1 + 100 of a portion of a highway stretch has an area of 100 sq.m. in cut while that of station 1 + 200 the area is 240 sq.m. in cut. At Station 1 + 100, the ground surface to the left of the centerline is flat and the height of the right slope stake above the grade line is one half that of the left, while that of Station 1 + 200, the height of the right slope stake is 3 times higher than that of the left slope stake. The center cut at Station 1 + 200 is one- half that of center cut at Station 1 + 100. The width of the roadway is 10 m, with a side slope of 2:1. 1. Determine the height of cut at the center of Station 1 + 100. 2. Determine the height of the right slope stake at Station 1 + 200. 3. Determine the volume between Station 1 + 100 and Station 1+ 200 by applying prismoidal correction.

At Station 1 + 100 of a portion of a highway stretch has an area
of 100 sq.m. in cut while that of station 1 + 200 the area is 240
sq.m. in cut. At Station 1 + 100, the ground surface to the left of
the centerline is flat and the height of the right slope stake above
the grade line is one half that of the left, while that of Station 1 +
200, the height of the right slope stake is 3 times higher than that
of the left slope stake. The center cut at Station 1 + 200 is one-
half that of center cut at Station 1 + 100. The width of the
roadway is 10 m, with a side slope of 2:1.
