Your Result Represents The Cubic Yards Of Concrete Needed To Cover An Area The Width And Length Measured With A Slab Of The Proposed Thickness.

Knowing this, you can accurately determine how many pallets of concrete you’re going to need for your project. But ensure to convert all the measurements to the same unit. How many 40lb bags of concrete.

This Means That A Pallet Of Concrete Roughly Covers 0.85 Cubic Yards (0.65 Cu M).

Pi = 3.14 r^2 = radius squared or radius x radius (radius is 1/2 the diameter) h = height in inches here's an example: Once you have that measurement, multiply the square footage by the height/depth in feet. Add the cubic yard volumes of every rectangle in the series, multiply by 105%, and round up to the nearest quarter yard.

How Do You Calculate Cubic Feet Into Yards?

Multiply area times the depth to get volume in cubic feet; To convert a quantity of a substance or material expressed as a volume to mass we simply use the formula: Instead of using a concrete calculator to figure your cubic yardage, you can do the math yourself with this formula:

40 Pound Bag Yields.011 Cubic Yards.

Below you'll find a written formula to calculate concrete yardage for concrete projects like: Enter the height of 4 feet (or 48 inches). 60 pound bag yields.017 cubic yards.

Convert All Numbers To Feet Before Doing The Calculation.

Calculate and the answer is 0.08 cubic yards for one concrete tube multiply 0.08 x 50 = 4 total cubic yards of concrete for 50 tubes note that this calculation is the volume of your tubes only and does not account for any overflow or loss at the bottom of your tubes. The concrete calculator formula to figure cubic yards for a square or rectangle shaped concrete slab is (length x width x thickness) / 27. Multiply the answer by 50 of concrete for 50 tubes (0.08 x 50).
