I am thinking about replacing my existing patio with a new concrete slab. I currently have 1X3 concrete pavers. I am new to this and am wondering how to go about starting/completing the project? In order to find out how much concrete I'll need do I use the formula of A=lXWX or what? Thanks alot for your help.
P.S. How thick should the slab be? It'll be roughly 10-15'in lenght and roughly 6'wide.
