Has anyone a rough idea of how much a 2' x 2' x 2" Concrete block
would weigh, please?

" A 1.5" thick standard concrete countertop has an approximate weight
of 18.75 pounds per square foot."

therefore a 1 foot thick countertop i.e. a 1 ft cube would be
8 times as much - 150 pounds

2 square feet = 8 1 foot cubes = 1200 lbs = 10.7 cwt

So Nick is correct.

[ Believe it or not concrete is heavier than granite according to
this site at least - Granite is approximately 18 pounds per square
foot. ]


You're going all over the place with this one, plus you are using an
American site, whose pounds, feet and everything else are different to ours.

2 square feet isn't 8 cubic feet, 8 cubic feet is...and a two foot by two
foot flag, 2 inches thick is exactly 43Kg, I lift them all day, every day.
