Find square footage
A 10x10 slab is 100 square feet before thickness is considered.
Convert thickness to feet
A 4 inch slab is 0.333 feet thick. Multiply area by thickness to get cubic feet.
Convert to cubic yards
Divide cubic feet by 27 to estimate cubic yards for ready-mix ordering.
Add waste
Add extra for uneven grade, forms, spillage, and small measurement differences.
FAQ
How many cubic yards for a 10x10 slab at 4 inches?
