Earthwork volume for a rectangular trench = L x B x D (m^3), where L = length, B = width, D = depth of excavation. Per IS 1200 Part 1, earthwork is measured in m^3. Includes excavation in all types of soil; bulking factor applies if payment basis is loose (excavated) volume rather than bank (in-situ) volume. Earthwork volume=L×B×D=150 m³.
