Get the count from the brick calculator or the concrete block calculator, then come here. The footing under either wall is still concrete, not mortar.
FAQ
How many bricks per bag?
Up to 37 standard bricks for an 80 lb bag of QUIKRETE Mortar Mix. 370 bricks is 10 bags. The word is “up to,” so a sloppy joint can take another bag.
How many blocks per bag?
Up to 13 standard 8×8×16 blocks per 80 lb bag on the current QUIKRETE data sheet. An older coverage chart said 12. Use 13 and still round up. Switch the form to blocks.
