How much do they weigh?

I'd say about as much as it does when it's sitting on a scale to find out.

Those would be known as bench plates, I think, not real "surface" plates. Good for such as layout work. They do not have the necessary ribbing to be stable as is a standard sort of surface plate.

111.6 lbs each according to an online calculator.
112.5 lbs each according to g-wizard.
I couldn't find a USPS flat-rate box/envelope that will hold one.

Is that weight supposing that they are solid, (which they are not), the bottom is hollow as can be seen in one of the pics.

Those are not surface plates. They were originally the bed of a paper cutter made by the Challenge Machinery Co..
I used to service this equpt.
No real surface spec. The bed supported a stack of paper (for printing) the a guillotine knife came down to trim the paper to size. I you look at the printing equpt auctions, these are readily available. Challenge "end of life" many models over the last 10 yrs

Still, they would make a fine bench plate for layout work.

I didn't notice that they are not solid.
