To find the cubic yards of screenings disposed of in a dumpster, first, it’s essential to calculate the volume of the dumpster in cubic feet and then convert that volume into cubic yards.

The volume of a rectangular dumpster can be calculated using the formula for volume, which is length × width × height. In this case:

- Length = 10 feet

- Width = 8 feet

- Height = 6 feet

Calculating the volume in cubic feet:

10 feet (length) × 8 feet (width) × 6 feet (height) = 480 cubic feet.

Next, to convert cubic feet to cubic yards, one must be aware that there are 27 cubic feet in one cubic yard (3 feet × 3 feet × 3 feet). Thus, the conversion process involves dividing the total cubic feet by 27:

480 cubic feet ÷ 27 cubic feet/cubic yard ≈ 17.78 cubic yards.

If this dumpster is used over a 30-day month and assumes that the dumpster is emptied completely once a month, you can multiply the cubic yard measurement by the number of months:

17.78 cubic yards/month × 30 days/month = about 533 cubic yards.

Thus, the accurate disposal
