When soil is excavated and placed in a dump truck, the volume increases because the soil expands with additional air voids from its compacted natural state, typically by a factor of 1.25 (see image below). How many dump truck loads (20 cubic yard capacity) are needed to haul the soil from an excavation that is 30 feet wide by 50 feet long by 10 feet deep? Note: round your number of loads up to the next whole number. 1.0 cubic yards in natural condition (in-place yards) = 1 25 cubic yards after digging (loose yards) = 0.90 cubic yard after compaction (compacted yards)
