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 do I figure out how many yards of concrete I need?
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 figure 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 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 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 area does a cubic yard cover?
1 Cubic Yard Covers Example: One cubic yard spread at a depth of 3 inches covers 108 sq feet.
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.
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 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 slab be?
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 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.
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 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 much will a cubic yard of concrete 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 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 weight can a 4 inch concrete slab support?
Typically we like to limit the weight to about 40 lb/sqft on an unknown 4″ slab. In most cases you can go to 80 lb/sqft in isolated spots, but unless you know roughly what the soil bearing and reinforcing is for that slab you might be looking at cracking.
