Concrete Calculator - How Much Concrete Do I Need? - The
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. To determine how many bags of concrete you will need divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards

Wearing rubber gloves scoop some cement mixture onto leaf. Spread to cover back of leaf pressing down lightly to remove air bubbles. Continue adding and spreading mixture over leaf until about 1 1/2 inches thick on middle of leaf thinning to about 1 inch thick at the edges.
Fundamentals of Concrete
The absolute volume of a concrete mix can be determined if the weight and bulk specific gravity of the components are known. For a concrete mix with 90-lbs of coarse aggregate with Gs = 2.65 60-lbs of fine aggregate with Gs = 2.63 25-lbs of cement and 12-lbs of water the absolute volume is computed as follows:
