Concrete measurement?
Question:I want to pour a concrete slab, 2x2x6 using 80lb bag of
concrete. How many bags would I need.
Answers:
2' x 2' x 6" is 2 cubic feet.
80 pound bag yields 0.60 cubic feet, so 4 bags with a bit left over. You will probably need it.
60 pound bags are .45 cubic feet, so it would take 5 bags.
it depends on the thickness of the slab, once you know the thickness the 80lb bags will state the amount needed in sq. ft.
if the slab is going to be 2ft. by 2ft. and six inches thick you will need 2 cubic feet of concrete. the bag should say how many cubic feet are in each bag. I think a 60lb bag has about 1 cubic foot of concrete
