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 do I calculate cubic yards?
Here’s how to do this: Convert the dimension in inches to yards (6 inches ÷ 36 inches = 0.167 yards) Convert the dimensions in feet to yards (12 feet ÷ 3 = 4 yards) Multiply the three dimensions together to find the number of cubic yards (0.167 x 4 x 4 = 2.67 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 thick should a concrete patio be?
Four inches is the minimum thickness for a concrete patio. You’ll want to make it six to eight inches thick if the patio will support a structure such as a gazebo or hot tub.
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 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.
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 many cubic yards are in a yard of concrete?
Now, we know that 1 cubic yard = 27 cubic feet, and then divide 108 cubic feet volume of concrete by 27. = 108 / 27 = 4 cubic yard concrete. You can try it by converting all units in the cubic yard also, Convert the dimension in inches to yards = 9” ÷ 36” = 0.25 yards.
What is a cubic yard of concrete?
Most concrete purchases will be made in cubic yards, which equates to 27 cubic feet. For example, a project measuring 10 ft in length by 10 ft in width with a depth of 3.5 in will be just over 1 cubic yard.
Whats the difference between cubic yard and yard?
What Is the Difference Between a Yard and a Cubic Yard? A yard measures a two-dimensional area, and a cubic yard measures three-dimensional volume, or how much a space can hold.
How many bags of concrete do I need for a 10×10 slab 4 inches thick?
The thickness of your 10′ x 10′ slab will determine just how many bags you need. The average thickness of a 10′ x 10′ concrete slab for a shed is 4 inches thick. At 4″ thick, your 10 x 10 slab will take 56 bags of concrete that weigh 80 lbs.
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.
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.
How many bags of concrete do I need for 2 yards?
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.
How many cubic yards of concrete are in a 50 pound bag?
Volume of a 50 lb bag of concrete:- a 50 lb bag of concrete yields 0.375 cubic feet volume which is approximately equal as 0.0138 cubic yards or 2.8 gallons or 10.62 liters volume of concrete.
How many yards are in a 90 pound bag of concrete?
90lb bag of premixed cement, sand and gravel as concrete is (90/133 = 0.676) around 0.676 cubic foot per bag, as we know there are 27 cubic feet in one cubic yard, so number of 90 lb bags of concrete are in a cubic yard = 27/0.676 = 40 bags.
