Armand pose la question : I am
planning to pour a concrete slab over an existing slab in my garage
which is very uneven, with a depth variation from 2 1/2 inches to 5 1/2
inches from level. I'm afraid to over estimate concrete since it will be
wasted but worse, I'm afraid to underestimate. I've broken the slab down
into four sections with the following being the four dimensions, can you
tell me how much concrete I will need please, I would very much
appreciate your help.
1 6ft/8in x 20ft x 4 1/2 in. thick
2 16ft/10in. x 20ft x 3 1/2 in. thick
3 6ft/6in. x 16in. x 5 1/2 in. thick
4 6ft/6in. x 8ft. x 4in. thick
