(Answered) Soil sampling results indicated the area impacted with lead

Academics

Soil sampling results indicated the area impacted with lead above action levels is 30 feet by 55 feet. The depth of the lead contamination plume is three feet below ground surface.

Solve for the minimum volume of soil that will be excavated in cubic yards?
If each dump truck can transport 18 cubic yards, determine how many dump trucks loads will be transported? For calculation purposes, add a 15% "fluff factor" (add to the volume that will be transported).
If the bulk density of soil is 1350 kg/m3 (84.3 lb/ft3), solve for the weight of the soil that will be transported to a disposal site in kilograms.
