The centre line of a proposed road of formation width 12.000 m is to fall at a slope of 1 in 100 from chainage 50 m to chainage 150 m. The existing ground levels on the centre line at chainage 50 m, 100 m and 150 m are 71.620 m, 72.340 m and 69.310 m, respectively, and the ground slope at 1 in 3 at right angles to the proposed centre line. If the centre line formation level at chainage 50 m is 71.220 m and the side slopes are to be 1 in 1 for cut and 1 in 2 for fill, calculate the volumes of cut and fill between chainage 50 m and 150 m.
