How many bags of cement is needed for 11 yards of concrete?

To determine how many bags of cement are needed for 11 yards of concrete, you first need to know the concrete mix ratio. A common mix is 1:2:3 (cement:sand:gravel). For a standard 80-pound bag of cement, it typically yields about 0.6 cubic feet of concrete. Since there are 27 cubic feet in a yard, 11 yards equals 297 cubic feet. Using a standard mix, approximately 7 to 8 bags of cement would be needed for this volume, depending on the specific mix and design requirements.
