How many cubic yards do I need to cover 13 ft by 9 ft 8 inches deep?

To find the volume in cubic yards, first convert the dimensions to feet. The area is 13 feet by 9 feet, which equals 117 square feet. The depth of 8 inches converts to 0.67 feet (8 inches ÷ 12). Therefore, the volume is 117 square feet × 0.67 feet = 78.39 cubic feet. Finally, convert cubic feet to cubic yards by dividing by 27 (since there are 27 cubic feet in a cubic yard), resulting in approximately 2.9 cubic yards needed.
