How much mulch do I need to fill a 10 foot by 10 foot area 2 inches deep?

To calculate the amount of mulch needed, first convert the dimensions to cubic feet. A 10-foot by 10-foot area is 100 square feet. For a depth of 2 inches, convert inches to feet (2 inches = 1/6 feet). Multiply the area by the depth: 100 square feet × 1/6 feet = approximately 16.67 cubic feet of mulch needed.
