Calculating Area Needed for One Year's Worth of MSW in US Landfills

[physicsss]

The US sends about 129 million tons of municipal solid waste to landfills. what landfill area is neeed for one year's worth of MSW if the landwill density is 800lb/yd^3, cell depth is 10 ft with one lift per year, and 80% of the cell is municipal solid waste. what is the area in acres/yr per 1000 people...

First of all, should I take it that 129 millions of MSW are sent to the landfill per year?

That is a reasonable assumption.
