To calculate the amount of gravel needed, first convert the dimensions to yards. The area is 14 feet by 40 feet, which is 560 square feet. The depth of 6 inches is 0.5 feet, so the volume in cubic feet is 560 square feet × 0.5 feet = 280 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 280 by 27, which equals approximately 10.37 cubic yards of gravel needed.
77/9 cubic yards for every inch of depth.
Total square yards: 31.1
280 / 9 square yards x 2 / 36 yards = 1.7284 cubic yards (about 1 3/4 cu yds)
