Concrete is mixture of cement, sand, gravel and water with some admixture in the required proportion, generally used for various concreting structure such as shed base, Patio, sidewalk, concrete road, slab, floor slab, column, beam and heavy structure bridge, dam, pool and also used in residential industrial commercial building.

You are preparing a ready mix concrete for casting of slab, Patio, sidewalk, shed base, roadways, pedestrian path, roadways, pavement, driveway, parking which shall be at different thickness at 3″, 4″, 5″, 6″, 8″, 10″ & 12″ thick then what will be their coverage per sq ft & how much area or ground a yard of concrete cover.

In United States volume of concrete measured in yard (short form of cubic yard) and their weight measured in pounds (lbs). When you will think about new project the different types questions comes in mind how much concrete i need for completion of projects, its depends on their coverage. Many of contractor will take or supply 5 to 10% more concrete than required.

A yard of concrete look like heaped of 3 feet long by 3 feet wide by 3 feet height which is approximately equal as 27 cubic feet. But generally of concrete structure will be at Different thickness such as 3″, 4″, 5″, 6″, 8″, 10″ & 12″.

Most of the concrete floors and slabs i need are 4 inches thick. This is a normal thickness for most garages, patios, walkways, and shed slabs. Others thickness such as 3″, 5″, 6″, 8″ & 12″ are also used. The amount of square feet you’ll get from a yard of concrete will be determined by how thick or depth your concrete slab is.

## How many square feet in a yard of concrete

If you want your a cubic yard of concrete to be described in square feet, multiply one cubic yard number by 27 to get measurement in cubic feet, then divide the total cubic feet by thickness or depth in feet to get your measurement in square feet such as square feet = (cubic yards × 27) ÷ thickness or depth in feet. For example convert one yard of concrete to square feet = (1×27) ÷ 0.25 = 108 square feet at 3″ depth.

How many square feet in a yard of concrete? A cubic yard of concrete contains 81 square feet at 4 inches thick, 108 square feet at 3 inches thick, 92 square feet at 3.5 inches thick, 65 square feet at 5 inches thick, 54 square feet at 6 inches thick, 40 square feet at 8 inches thick, 32 square feet at 10 inches thick and 27 square feet at 12 inches thick.

### Square feet to yards of concrete

There are approximately 81 square feet to yards of concrete at 4 inches thick. If the concrete slab or patio or garages, walkways, and shed slabs is 4 inches thick then you will get 81 square feet from a cubic yard of concrete.

To convert square feet to cubic yards of concrete, you simply multiply your square footage (Length × Width) figure by the height or Thickness of the slab (in feet) to get a volume measurement in cubic feet. You then divide the total by 27 to get your measurement in cubic yards.

Formula for Square feet to yards of concrete: Yards of concrete = [ Square footage × Height in feet] ÷ 27.

For example:- To convert 100 square feet of slab to yards of concrete at 4″ thick. Ans. Maths calculation: 1) height in feet = 4/12 = 0.33 feet, 2) Cubic feet of concrete = 100 × 0.33 = 33 cubic feet, and 3) Yards of concrete = 33 ÷ 27 = 1.22 cubic yards.
