Concrete weighs about 150#'s per cubic foot. Given that your measurements are 2'x2'x4', the block contains about 16 cubic feet. 16 cubic feet of concrete at 150#'s is about 2400#'s per block.
Density of concrete varies, but those dimensions would yield 31.3 cubic feet of concrete at an average 133 lbs per cubit foot - making 4,100 lbs (or around 2 tons).
