A cubic foot of limestone rocks weighs around 96 to 150 lbs (44 to 68 kg). On the other hand, a cubic foot block of limestone cut from a large piece of limestone would weigh around 168 lbs (76 kg). The difference in solid and crushed limestone weights depends on the void spaces within the considered cubic foot volume.
