Concrete Slab Calculator 10' x 10' x 6"

A 10 x 10 foot concrete slab 6 inches thick is 100 sq ft and needs 50 cubic feet of concrete: 1.85 cubic yards. Change any size to recalculate. The calculator comes filled in with 10 ft x 10 ft x 6 in. Enter your own width, length and thickness to get the surface area and the volume of concrete in cubic feet and cubic yards, with the concrete added to the materials, ready to price the job in a GetCost estimate. How to calculate it: multiply the length by the width by the thickness, all in feet (6 inches = 0.5 ft): 10 x 10 x 0.5 = 50 cubic feet. Divide by 27 to get cubic yards: 50 / 27 = 1.85. That is the exact volume - order about 10% more for waste, spills and uneven ground (about 2 cubic yards here). An 80 lb bag of concrete mix makes about 0.6 cubic feet, so this slab takes about 84 bags, or 92 with the extra 10%. Other sizes: the 10 x 10 x 4 inch and 20 x 20 x 6 inch slab calculators, or the Concrete Slab Calculator for any size, with labor.
