Step 1: First calculate the amount of solid waste produced during the period of 20-year before the land is converted to the park. Now we have to convert the total waste generated per day: =5lbm/capita-day x10,000 people = 50,000lbm/day Now after calculating the total waste generated per day, we have to find the total waste generated during 20years. 50,000lbm/dayx365days/year ×20years = 365,000,000lbm Now in this step, we will convert the density of the solid waste which is in the pound per cubic yard, of the volume of the landfill. = 30acres x43,560sqft/acre x(19)sqydsqftx6ft = 87,120cubic Step 2: To find the total weight of waste we will use the formula for this: Total weight of waste = Density of the solid waste * Volume of the landfill = 1,000lbm/yd3x87,120cubic yards = 87,120,000lbm Step 3: Last, we have to find out the Time that will take to fill the landfill to a uniform height of 6ft with the amount of solid waste. But things first, we will use the formula to find out the number of days: Number of days = Total weight of the solid waste / Total solid waste generated per day = 87,120,000lbm/50,000lbm/day =2,100days

Question
- A town has a current population of 10,000, which is expected to double in 15 years. The town intends to dispose of its municipal solid waste in a 30-acre landfill that will be converted to a park in 20 years. Solid waste is generated at the rate of 5 lbm/capita-day. The average compacted density in the landfill will be 1000 lbm/yd3. Disregarding any soil addition for cover and cell construction, how long will it take to fill the landfill to a uniform height of 6 ft.
- 2100 days
- 4200 days
- 6300 days
- 9500 days
Please I want you to solve this question and I don't want it to be similar to the one I upload in picture because this is wrong.

First calculate the amount of solid waste produced during the period of 20-year before the land is converted
to the park.
Now we have to convert the total waste generated per day:
=5lbm/capita-day x10,000 people
= 50,000lbm/day
Now after calculating the total waste generated per day, we have to find the total waste generated during
20years.
50,000lbm/dayx365days/year ×20years
= 365,000,000lbm
Now in this step, we will convert the density of the solid waste which is in the pound per cubic yard, of the
volume of the landfill.
= 30acres x43,560sqft/acre x(19)sqydsqftx6ft
= 87,120cubic
Step 2:
To find the total weight of waste we will use the formula for this:
Total weight of waste = Density of the solid waste * Volume of the landfill
= 1,000lbm/yd3x87,120cubic yards
= 87,120,000lbm
Step 3:
Last, we have to find out the Time that will take to fill the landfill to a uniform height of 6ft with the amount
of solid waste.
But things first, we will use the formula to find out the number of days:
Number of days = Total weight of the solid waste / Total solid waste generated per day
= 87,120,000lbm/50,000lbm/day
=2,100days
