Question

1. Stephen works for an environmental protection agency

responsible for toxic waste cleanup. Stephen has to

remove the top 24" of contaminated soil in order to make

sure the soil is not a health hazard. The soil covers a

1200' x 1500'lot. How much soil must be removed?

Answer 1

Area to be removed = 3600000 feet³

Explanation:

We need to calculate the volume of soil to be removed. We have been already provided with area of the lot in feet.

Total Area of soil = 1200' x 1500'

Where soil to be removed is given in inches, convert it into feet

Soil to be removed = 24''=2'

Multiply both the the value to get the volume of soil to be removed so the soil is not a health hazard

Area to be removed = 1200' x 1500' x 2'

Area to be removed = 3600000 feet³
