We are digging a hole to build a building. Calculate the energy needed to bring the soil to surface level. Remember the sides of the excavation lie at 45 degrees. Else, the whole would be constantly refilling itself.

Given,

density of soil= 140 lb/ft^3

The foundation is rectangular,

Breadth= 300'

width=30'

Depth=18'

Excavation includes 45 degree slope

CAT 329 Excavator
