How much bark mulch should you order for an area that is 20' wide, 100' long, and 3" deep?

• A. 10.5 yd^3
• B. 15.2 yd^3
• C. 18.5 yd^3
• D. 25.0 yd^3

Answer: (C)

To determine the amount of bark mulch needed for an area that is 20 feet wide, 100 feet long, and 3 inches deep, you start by calculating the volume of mulch required in cubic feet and then convert that volume into cubic yards. 1. First, calculate the volume in cubic feet. The formula for volume is Length x Width x Depth. - Length = 100 feet - Width = 20 feet - Depth = 3 inches (which needs to be converted to feet for consistency in measurements: 3 inches ÷ 12 inches per foot = 0.25 feet) So, the calculation would be: Volume = 100 feet x 20 feet x 0.25 feet = 500 cubic feet. 2. Now, convert cubic feet to cubic yards. There are 27 cubic feet in one cubic yard. - Therefore, you divide the volume in cubic feet by 27: - 500 cubic feet ÷ 27 cubic feet per cubic yard ≈ 18.52 cubic yards. Since the answer closest to this value is 18.5 cubic yards, it makes sense that this would be the correct answer. The calculation is a straightforward method of determining the volume

1. First, calculate the volume in cubic feet. The formula for volume is Length x Width x Depth.

• Length = 100 feet

• Width = 20 feet

• Depth = 3 inches (which needs to be converted to feet for consistency in measurements: 3 inches ÷ 12 inches per foot = 0.25 feet)

So, the calculation would be:

Volume = 100 feet x 20 feet x 0.25 feet = 500 cubic feet.

2. Now, convert cubic feet to cubic yards. There are 27 cubic feet in one cubic yard.

• Therefore, you divide the volume in cubic feet by 27:

• 500 cubic feet ÷ 27 cubic feet per cubic yard ≈ 18.52 cubic yards.

Since the answer closest to this value is 18.5 cubic yards, it makes sense that this would be the correct answer. The calculation is a straightforward method of determining the volume
