How much mulch to cover 260 square foot 3 inches deep?

To cover 260 square feet with 3 inches of mulch, you'll need about 0.75 cubic yards of mulch. Since 1 cubic yard equals 27 cubic feet, first convert the depth from inches to feet (3 inches = 0.25 feet). Then, calculate the volume: 260 sq ft x 0.25 ft = 65 cubic feet. Converting this to cubic yards, divide by 27: 65 cubic feet ÷ 27 = approximately 2.41 cubic yards. Therefore, you'll need about 2.5 cubic yards of mulch to achieve the desired coverage.
