Concrete is normally used as a structural component in building projects and is a mix of materials, while cement is just one ingredient in concrete, acting as a binder.
Most concrete bags are 4 inches thick, so if you lay the bags end-to-end, you can measure out the number of concrete mix bags you will need for a designated square footage.
Concrete mix does not expand when water is added, so a good rule of thumb is that the area the bag of concrete mix takes up will be the same size it will be when water is added and it hardens.
This rule of thumb is best used when laying a 4-inch thick concrete pad.
