Imagine a town where 5000 households each fill two 60 gallon

Imagine a town where 5000 households each fill two 60 gallon containers of MSW per week. What volume would this MSW occupy in a landfill. Assume that 15% of the volume is occupied by the cover dirt. Assume density of MSW when collected is 225 lb/yd^3 and is 1,100 lb/yd^3 in the landfill.

a. 516.1 m^3

b. 576 yd^3

c. 765 m^3

d. none of the above

Solution

d)none of th above.....

total volume of MSW= 60*5000*.85*0.0049 yd3=1249.5yd3

As mass is always same,

We have req volume= (225/1100)*1249.5=255.5 yd3
