figuring cubic feet for cement | 1.23 | 0.3 | 8373 | 95 |

An 80-pound bag of concrete makes 0.6 cubic feet. A cubic foot of any material is enough to fill a box that is 1 foot wide, 1 foot tall and 1 foot long. In order to determine the volume of concrete required for a project, a worker must determine the surface area and thickness of the concrete.

Concrete Weight: 1 Cubic Foot of Concrete weighs ~150 lbs. 1 Cubic Yard contains 27 cubic feet. 1 Cubic Yard of Concrete weighs ~4,050 lbs.

Divide that number by 27 and you will have the cubic yards for the slab. For the footings, take the 42.13 cubic feet calculated earlier and divide by 27 (1 cubic yard of concrete equals 27 cubic feet). The final formula is 48 x 1.33 x .66 = 42.13 divided by 27 = 1.56 cubic yards of concrete.
