Just follow these steps: 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 you figure cubic yards of concrete?
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 many yards of 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.
What is the formula for figuring out 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 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 many square feet is a yard of concrete 6 inches thick?
One Cubic Yard of Concrete: 4-inches thick – covers 81 square feet. 5-inches thick – covers 65 square feet. 6-inches thick – covers 54 square feet.
Do you need rebar for 4 inch slab?
The thickness of rebar should be no more than 1/8 that of the slab, so a 4” slab shouldn’t have steel greater than #4 or 1/2″ bar. It’s best to check with a Structural Engineer if your slab will bridge or cantilever. What is this? For 4” concrete slabs used for driveways and patios, #3 rebar is common.
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 an 80 pound bag of concrete cover?
80 lb bag of concrete cubic feet 80 lb bag of concrete yields 0.60 cubic feet which is approximately around 0.0222 cubic yards that will cover around 3.6 sq ft area up to standard depth of 2 inch excavation or backfills, and for 1 cubic feet of landfill you will need 1.66 bags of 80 lb concrete.
How much does a cubic 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 much cubic yards do I need?
Length in feet x Width in feet x Depth in feet (inches divided by 12). Take the total and divide by 27 (the amount of cubic feet in a yard). The final figure will be the estimated amount of cubic yards required.
How many square feet is 16 cubic yards?

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 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 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.
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 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 do you convert square feet to cubic yards?
To convert square feet to cubic yards, you simply need to know the height or depth. Once you have that measurement, multiply the square footage by the height/depth in feet. Divide this number by 27 (the number of cubic feet in a cubic yard) to get a measurement in cubic yards.
