1. (15 points) Suppose Monongalia County, which has a population of 105,612 is planning anew landfill that will accept the county's waste for the next 20 years. Assume the county's

residents generate an average of 2.0 kg of solid waste per person per day, which is the U.S. average. The county plans to use a ratio of cover and compacted waste to compacted waste of 1.5. If the density of the compacted waste will be 550 kg/m³, what landfill volume is needed to accommodate the county's waste generation for 20 years?
