10×10 concrete slab: what to expect
A 10×10 slab covers 100 square feet. At the standard 4" thickness it takes about 1.36 cubic yards of concrete once you allow 10% for waste, which is roughly 62 × 80 lb bags if you mix by hand. Stepping up to 6" — sensible if it'll carry a vehicle — raises that to about 2.04 cubic yards.
Budget around $550 – $1,200 to have a 4" slab this size poured and finished by a contractor, or roughly $230 – $433 in ready-mix if you're doing the labor yourself. On top of the concrete you'll need about 1.42 yd³ of gravel base and 7 sticks of rebar.
