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 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 how much concrete I need for countertops?
Calculating Concrete Countertops Determine the thickness of your concrete slab. Multiply the length and width to determine square footage. Convert the thickness from inches to feet. Multiply the thickness in feet by the total square footage to determine cubic feet. Divide by 27 to convert cubic feet to cubic yards.
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.
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 bags of concrete do I need for a 10×8 slab?
Regarding this, “how many bags of concrete do I need for a 10×8 slab?”, at 4 inches thick, generally you will need approximately either 58 bags of 60lb or 45 bags of 80lb of premixed concrete for a 10×8 slab, at 5 inches thick slab, either 73 bags of 60lb or 56 bags of 80lb premixed concrete are required, while at 6.
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 many 80lb bags of concrete do I need for a 10×10 slab?
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 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 square feet does a 30 kg bag of concrete cover?
Regarding this, how many cubic feet are in a 30kg bag of concrete, as 60kg concrete = 1 CF, so a bag of 30kg concrete = 30/60 = 0.50 CF, so approximately there are 0.50 cubic feet in a 30kg bag of concrete.
How many bags of concrete do I need for a 10×12 slab?
Regarding this, “how many bags of concrete do I need for a 10×12 slab?”, at 4 inches thick, generally you will need approximately either 86 bags of 60lb or 67 bags of 80lb of premixed concrete for a 10×12 slab, at 5 inches thick slab, either 109 bags of 60lb or 84 bags of 80lb premixed concrete are required, while at 6.
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 yards of concrete does a concrete 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 much area 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 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). Most cement trucks hold between eight and 14 cubic yards.
