11. The centerline of a highway cutting is on a 90-m radius curve. The original ground surface is level. The cutting is to be widened by increasing the formation width from 6 m to 9 m with an excavation to be on the inside of the curve, retaining the existing slope of 1.5:1. If the depth of the formation increases uniformly from 2.5 m at station 0+200 to 5 m at station 347.55 m, calculate the volume of earthwork between these two stations.

A cross-section is to be taken at chainage 1225 m, where the depth of dig to the proposed formation level is to be 4.82 m. At this crosssection, the transverse slope at right angles to the proposed centre line falls from left to right but changes at the proposed centre line from a fall of 1 in 11 to a fall of 1 in 17.
