How do I calculate how much concrete I need for a slab? Measure the area in feet. Multiply length by width, and then by thickness. Divide the resulting number by 27 to find cubic yards.
How much concrete do I need for a 10×10 slab?
The amount you will need for a 10 x 10 slab is 1.3 cubic yards, we always add an extra 10% to allow for any slab depth variations or spills that may occur.
How many yards of concrete do I need for a 24×24 slab?
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”. Your answer should be 7.11 yards. Note: The Concrete Volume Calculator can also be used to determine yardage for aggregate products.
How do I calculate how much concrete I need?
Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness.Here’s what the math looks like for a 10′ by 10′ concrete patio: 10 x 10 = 100 square feet. 4 ÷ 12 = .33. 100 x .33 = 33 cubic feet. 33 x .037 = 1.22 cubic yards.
What is a yard of concrete?
How much concrete is in a yard? Concrete volume is measured in cubic yards. When poured on a perfectly level surface, one cubic yard will cover 27 square feet at one foot thick.
How many square feet is a yard of concrete 4 inches thick?
One Cubic Yard of Concrete: 4-inches thick – covers 81 square feet.
How much area does a 40 lb bag of concrete cover?
Regarding this, how much does a 40 lb bag concrete cover, as 133 lb concrete = 1 CF, so a bag of 40 lb concrete = 40/133 = 0.30 CF, therefore, a 40 lb bag concrete approximately cover around 1.8 square feet area upto depth of 3 inch.
How much does it cost to pour a 24×24 slab of concrete?
A typical 24×24 garage slab costs between $3,057 and $5,944 with prices ranging from $5.31 to $8.31 per square foot for a 4” reinforced slab of concrete, and $6.83 to $10.32 per square foot for a 6” slab of reinforced concrete.
How thick do I need my concrete?
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
How many yards of concrete can a truck hold?
Each cubic yard costs about $65. However, a fully loaded cement truck will hold 10 cubic yards—and partial “short” loads cost $15 to $20 extra for every cubic yard less than a full load.
How do I figure cubic yards?
You can easily calculate cubic yardage by converting all three dimensions of your material into yards and multiplying them. For example, if you dig up a flower bed that is 9 feet long, 3 feet wide and 12 inches deep, you will have one cubic yard of dirt.
What are the dimensions of a cubic yard of concrete?
Likewise, a cubic yard (yard = 3 feet) is a cube 3 feet by 3 feet by 3 feet or 27 cubic feet.
How much cement do I need for a 12×12 slab?
Regarding this, “how much concrete do I need for a 12×12 slab?”, at 4 inches thick, generally you will need approximately 1.76 cubic yards or 47.52 cubic feet or 1.35 m3 (either 104 bags of 60lb or 80 bags of 80lb) of premixed concrete for a 12×12 slab, at 5 inches thick slab, 2.22 cubic yards or 59.90 cubic feet or.
How do I calculate square feet into yards of concrete?
To convert square feet to cubic yards, you simply multiply your square footage figure by the height or depth of the area (in feet) to get a volume measurement in cubic feet. You then divide the total by 27 to get your measurement in cubic yards.
How much space is a yard?
Under the United States’ Customary System, 1 yard is equal to 3 feet or 36 inches. And a cubic yard is the volume of material that fits in a space that is 1 yard wide by 1 yard deep by 1 yard high. This is important because quite a few common materials are measured in cubic yards — here are some of them: Concrete.
What does 1 yard of concrete weigh?
Concrete Weight per Cubic Yard A solid slab of concrete weighs 4,050 pounds per cubic yard. A cubic yard of broken up concrete weighs 2,025 pounds.
How many square feet is 3 cubic yards?

How many 80 lbs bags of concrete make a cubic yard?
One 80lbs bag of Quikrete Concrete Mix will yield approximately . 60 cu ft. So it will take 45 bag to equal one cubic yard of concrete. If you have a project over a 1/2 a cubic yard you should consider our Mix On-site Concrete especially if you are hand mixing.
What is ideal temperature to pour concrete?
Experts agree—the best temperature to pour concrete is between 40° – 60°F. When temperatures dip below 40°F, the chemical reactions that strengthen concrete slow down and can lead to weaker concrete.
