What does a 24 x 24 x 3 concrete block weight?

The weight of a concrete block can vary based on its composition and density, but a typical concrete block weighs around 150 pounds per cubic foot. A 24 x 24 x 3 inch block has a volume of 1.5 cubic feet. Therefore, it would weigh approximately 225 pounds (1.5 cubic feet x 150 pounds per cubic foot).
