48bags .  One 80-lb bag of concrete mix is 1 cubic foot.  Your area ia 96 sq ft, and times 1/2 foot thick is 48 cubic feet, or 48 bags.

Answer 2

A cubic yard of concrete is 54 sq. feet of 6" thick cement (premixed with aggregate and sand). I believe Redi-Mix is 23 bags per cubic yard.

Answer 3

Answer 4

u need 1 3/4 yds of concrete to pour this, the bag will tell u somewhat, bt i know that it takes 4 bags to fill a contractor wheelbarrel and 1 wheelbarrel is about 1/8 of a yd..

Answer 8

Call the local cement company, They will help you do the math. It don't matter if they bring it or you mix it. They may give you a deal on the cement and the right sand/gravel. You will have to consider if someone is going to build on it in the future, so you will need the right stuff to support a load, You can ask them to consider you for an over run, That is if they have to dump a load before it sets up in the truck. Put you on the list!
