Estimate Amount Of Concrete Needed

Concrete cost estimator helps homeowners and contractors calculate the amount of pre mixed concrete needed for footings slabs and walls round columns as well as concrete stairs.

Estimate amount of concrete needed.

100 x 33 33 cubic feet. Mark the area that will need concrete and divide it into smaller areas. Learn the required concrete density or estimate it based on the chosen concrete mix. You get 1 3 cu.

Multiply the length 10 ft by the width 10 ft by the depth 35 ft or 4 in and divide it by 27 the number of cubic feet in a cubic yard. For concrete the formula for volume is as follows. To determine how many bags of concrete you will need divide the total cubic yards needed by the yield. The formula for cubic yards is this.

Calculate the volume of concrete you need in cubic yards. This free concrete calculator estimates the amount of concrete necessary for a project and can account for different shapes and amounts of concrete. Calculate the volume of the area after determining the shape of the area see the chart below by multiplying in the thickness of the concrete. Enter the dimensions of your project and you will get results in cubic yards as well as the number of concrete mix bags needed for the job.

33 x 037 1 22 cubic yards. Essentially you are solving for volume and then converting to cubic yards. Length x width x thickness. Multiply the volume by the density in the same units optional estimate the amount of readymix concrete you would need.
