Was this Answer Helpful ?An 80 lb. bag of QUIKRETE Concrete Mix yields approximately 0.6 cubic feet of concrete. A space 16 ft. x 1.5 ft. (18”) x 0.167 ft. (2”) will require approximately 4 cubic feet of concrete, or approximately 7 80 lb. bags of QUIKRETE Concrete Mix to fill. Yields are approximate and will vary based upon waste, uneven sub-grade, etc.
Was this Answer Helpful ?6- 80# bags should do it.
Was this Answer Helpful ?The math works out to 6 2/3 bags of 80# Quikrete. You will have to purchase 7 bags. This figure assumes your measurements, grade and form preparation is spot on. It never hurts to pick up a couple of extra bags just in case...they are always returnable to Lowe's if you don't use them.
