Cinder blocks weigh very little. Do you mean concrete block?

I am really not into that kind of stuff. Whatever it is, it weighs around
10 # .

That's concrete. Concrete blocks look like, and are as heavy as, well,
concrete. Cinder blocks are black (or maybe other dark colors), very
lightweight, and full of little holes -- like, um, cinder.

Not really relevant, but recently in Germany I saw "foamed" concrete
blocks, which had small air bubbles in them like foamed dielectric coax
insulation. They're considerably lighter weight than solid ones.
