The product of a multiplication problem is square 255 what do you know about the fat people?

It seems there may be a misunderstanding or miscommunication in your question. The product of a multiplication problem being 255 refers to a number and its factors, while the mention of "fat people" doesn't relate directly to that mathematical concept.

If you are referring to the mathematical property of the number 255, it is important to note that 255 is an odd number and can be factored into primes (3, 5, and 17). If you're looking for patterns, information, or statistics about body weight or health, it's a different topic entirely. Could you please clarify your question or provide more context?
