The environmental protection agency is attempting to revive 3 acres of contaminated soil by replacing the top 24 inches of the soil. trucks with a hauling capacity of 28 cubic yards of soil are hired to remove the contaminated soil. how many full truckloads of contaminated soil will be hauled away?

346 trucks are needed

Step-by-step explanation:

We know that one acre equals 43560 feet ^ 2

In this case the area is 3 acres. So:

We know that 1 foot equals 12 inches. So:

So the volume of the contaminated area is:

In a cubic yard there are 27 cubic feet. So:

Finally if we have a volume of and each truck can transport then the amount of trucks x we need is:

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
