The formula is in feet and is L x W x H (/27). This formula will give you the estimated cubic yardage needed to do your project. For example if you have a concrete slab 24' L x 24' W x 6" thick, the formula would read like this; 24 x 24 = 576 x .5 = 288 divided by 27 = 10.67 cubic yards.

The cement industry was further affected by the maturing of the gas industry. Gas production levelled off as competing forms of energy, particularly electricity, arrived on the scene, and producers became more cost conscious. The producer gas/water gas process was increasingly used to improve gas yields, and this consumed coke.

A solid, unbroken slab of concrete weighs about two tons (or 4,000 pounds) per cubic yard. Breaking up concrete roughly halves the total weight per cubic yard to about one half ton (or about 2,000 pounds). How many bags of concrete are in a yard? To produce one yard of concrete, you'll need to use about 45 80-pound bags (or 90 40-pound bags).
