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 a yard of concrete?
There’s a pretty simple formula. Take the length in feet times the width and height of the wall to figure your cubic footage. Then divide that figure by 27 to get your cubic yards (because there are 27 cubic feet in a cubic yard).
How do I figure how much concrete I need?
Multiply the width times the length times the height (W × L × H), or use our volume calculator to find the cubic feet. Convert the volume to cubic yards from cubic feet. To do so, divide the cubic footage by 27 to get the yards of concrete needed.
How much concrete does a cubic yard cover?
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 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 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 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.
What is the formula for figuring out concrete?
Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.
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 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 many cubic feet is an 80 lb bag of concrete?
45 cubic feet and an 80-pound bag yields . 60 cubic feet. One 50-pound bag of Quikrete Fast Setting Concrete Mix yields about . 375 cubic feet.
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 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 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 much concrete do I need for a 30×30 slab?
18 yards of 3000 psi concrete mix @ 135.00 per yard. Wire mesh reinforcement. A double row of #4 rebar around the edges. Labor to form the slab.
How thick should a concrete driveway be?
As for thickness, non-reinforced pavement four inches thick is standard for passenger car driveways. For heavier vehicles, a thickness of five inches is recommended. To eliminate standing water, the driveway should be sloped towards the street a minimum of one percent, or 1/8 inch per foot, for proper drainage.
Why is concrete so expensive?
As more areas become industrialized—and as there grows a greater need for durable building materials to withstand severe weather and long-term wear—the demand for concrete has significantly increased. This alone has affected the price of concrete over the years.
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 square feet are in a cubic yard?
If you want your cubic yards to be described in square feet, multiply the cubic yard number by 27. This is because a yard is three feet, and a cubic measure is obtained by multiplying three numbers together (3 x 3 x 3 = 27).
How many bags of concrete do I need for a 4×4 slab?
As per calculation, for a 4×4 slab at 4 inch thick, generally you will need approximately either 12 bags of 60lb or 9 bags of 80lb of premixed concrete, at 5 inches thick slab, either 15 bags of 60lb or 11 bags of 80lb premixed concrete are required, while at 6 inches thick slab, either 18 bags of 60lb or 14 bags of.
