do you get six containers of 25 cubes

No, I got one container of 25 cubes which cost me $9.00. I received three containers of chicken bouillon for $9.00. Watch out for price gouging.

What is the percentage of salt content please?

the package states that the sodium content is 38% (910mg)

What happened, Herb ox? Some of us can't consume whey nor whey based products. We are grateful for no msg, but whey is bad too.

This seems more like a comment rather than a question to me. If a product contains whey and you are sensitive to it it’s probably best to look around for an alternative. How fortunate for you that whey is plainly listed as a component so you can avoid it.
