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
