How much mulch is needed for 26ftx30ft 4in deep?

To calculate the amount of mulch needed, first convert the dimensions to cubic feet. The area is 26 ft x 30 ft, which equals 780 square feet. For a depth of 4 inches, convert that to feet (4 inches ÷ 12 inches/foot = 0.33 feet). Multiply the area by the depth: 780 sq ft x 0.33 ft = 257.4 cubic feet of mulch is needed.
