How to figure yards of cement needed. Learning how to calculate the amount of concrete needed is easy when using our concrete formula and online concrete calculator. Next convert the volumes into cubic yards or cubic meters since thats how concrete is measured. Multiply the answer by 50 of concrete for 50 tubes 008 x 50.
Multiply the length by the width to determine square footage. To figure concrete yardage start by breaking your project up into multiple rectangular prisms. Then convert all of the measurements for each prism to the same unit and find the volume of each prism by multiplying its length width and height.
Multiply the thickness in feet by the square footage to determine. Mark the area that will need concrete and divide it into smaller areas. Simply enter in the desired width length and concrete thickness.
The best way to calculate how much concrete youre going to need in cubic yards is to do the following. Convert the volume from feet to cubic yards to get the number of cubic yards of concrete youll need. 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.
Measure the length and width that youd like to cover. You can also use our volume calculator to find cubic yardage of a space. To do so divide the cubic footage by 27 to get the yards of concrete needed.
Convert the thickness from inches to feet. How to calculate concrete. The calculation that you get is the volume of your tubes only and does not account for any overflow or loss at the bottom of your tubes.
Press calculate and you have the answer. Multiply the width times the length times the height w x l x h.
