For example, let's calculate how much concrete is needed for a 5-inch thick rectangular driveway, 60-feet long (length) and 18-feet wide (width). The area of the driveway is 1,080 square feet (60-feet x 18-feet). According to the table above, one cubic yard of concrete placed at a thickness of 5-inches covers 65 square feet. In a perfect universe, our 1,080 square foot driveway will need exactly 16.62 cubic yards of concrete (1,080 square feet / 65 square feet equals 16.62 cubic yards).
