UPDATE: I made this WAY simpler... watch this video instead: • The Easiest Way to Calculate Concrete Online Concrete Classes: https://decorativeconcreteschool.com In this video, I will show you how to quickly calculate how many yards of concrete you will need without using a concrete calculator. -------- Example from the video: 20x10 patio = 200 square feet 200 ÷ 81 = 2.5 cubic yards @ 4" thick. To convert this number for a slab with a different thickness do the following: 1" thick slab = 2.5 yards X 0.25 = 0.625 cubic yards 2" thick slab = 2.5 yards X 0.50 = 1.25 cubic yards 3" thick slab = 2.5 yards X 0.75 = 1.875 cubic yards 4" thick slab = 2.5 yards X 1.00 = 2.5 cubic yards 5" thick slab = 2.5 yards X 1.25 = 3.125 cubic yards 6" thick slab = 2.5 yards X 1.50 = 3.75 cubic yards 7" thick slab = 2.5 yards X 1.75 = 4.375 cubic yards 8" thick slab = 2.5 yards X 2.00 = 5 cubic yards Our favorite tools & camera gear http://dcva.us/favtools Our podcast, Hacking Concrete: http://dcva.us/podcast Follow me on Instagram: / timdcva Follow me on Twitter: / timdcva Follow Landon on Instagram: / modernpolishedconcrete Our concrete companies: http://decorativeconcreteofvirginia.com http://modernpolishedconcrete.com Contact me: Tim Seay c/o Decorative Concrete of Virginia 14719 Wards Rd.
