Essentially you are solving for volume and then converting to cubic yards.
Estimate amount of concrete needed.
Length x width x thickness.
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.
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.

Mark the area that will need concrete and divide it into smaller areas.
Multiply the volume by the density in the same units optional estimate the amount of readymix concrete you would need.
Estimate the volume of concrete needed using geometrical formulas and the construction plans.
33 x 037 1 22 cubic yards.
The formula for cubic yards is this.
For concrete the formula for volume is as follows.
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.
The best way to calculate how much concrete you re going to need in cubic yards is to do the following.
Calculate the volume of concrete you need in cubic yards.
To determine how many bags of concrete you will need divide the total cubic yards needed by the yield.
100 x 33 33 cubic feet.
