A topographic survey of a proposed highway shows that the centerline crosses a small valley between Sta. 20 + 032 (Elevation 75 m) and Sta. 20 + 070 (Elevation 74.5 m). The bottom of the valley is at Sta. 20 + 047 ( Elevation 63.2 m). The grade line of the proposed highway passes the ground points at the edges of the valley (Sta 20 + 032 and Sta 20 + 070) and the section at any of these stations are three level sections with width of road base of 10 m and side slope of 2:1. The sides of the valley can be assumed to slope directly to the lowest point from the edges. 1.

Volumes

Volume usually is the dimensional quantity that involves the evaluation of any three-dimensional figure enfolded inside a closed space. The SI unit (International System of Units) of volume is m3 and the dimensional unit of volume is [L3]. For estimation of the volume of any figure, various formulae are used. Another application of volume includes the reference in the sound levels, the higher the sound intensity, the louder the sound heard, and hence, the larger the volume. The SI unit of sound volume is decibels (dB).
