Concrete footers, more rebar less thickness?
I was told I need 24" wide but 12" deep footers with #4 @ 6 o.c. Now I am wondering if putting in 3 bars of rebar or maybe 2 by 2 above each other would make the footer equally strong with less concrete. Lest say only 8" deep. I have looked online but can not find a calculator I understand to calculate the strength of the footers. I guess what I am really asking is more rebar a substitute for thickness.

adding more steel to a footer will increase the flexural strength but NOT compressive strength,,, adding more steel is no substitute for any reduction in size from original dwgs
