2020 Crushed Stone Calculator: 3/4 inch rock HomeAdvisor
Jan 20, 2021As an example, a 10foot wide, 20foot long driveway is a 200square foot area. Then, multiply the area by the depth. For instance, if you are using four inches of crushed stone under a patio area or for a driveway, four inches converted to feet is .33. So, our calculation is .33 x 200 ÷ 27, or cubic yards.
