The quantity of cement in concrete depends on various factors. However, in most cases 250 – 500 kg of cement for one cubic meter of concrete is needed. Usually, weight of one cement bag is 25 kg. This means that for one cubic meter of concrete 10-20 bags are needed.

You will need to calculate the cubic yardage of the pour you are making. There are 27 cubic feet in a Cubic Yard 3'X3'X3'=1cubic yard. There will be a chart on the bags telling you how many bags you will need for your yardage.

Measure the wideth and length of the area, then multiple together. Multiple the sum of the length and wideth by the depth you want. 80 bags equal 2/3 cubic feet.
