Cooks Standard 02616 Professional Grade Lid 30 Quart Stainless Steel Stockpot, Silver

What is the diameter of the bottom outside of the 30 quart pot, please? I am confused with 3 different measurements for a round pot.

Can you please tell me for the 20qt pot, what are the measurements without handles or lid, and width with the handles?

Any reason why it wouldn't be good for making soup? i use meat fromf turkey legs and lots of veggies so i end up with not enough stock in my pots.

dimensions please.... does it hold 3 or 4 qt jars? Does it have a canning rack for the bottom? Has anyone used it on a glass cooktop?
