Cast Concrete Block:
Choose a block made specifically for freestanding walls, not retaining walls or pavers. To calculate how many blocks you need, multiply the length of the wall, in inches, by the height, and divide that figure by the area (length x height) of the side of one block. Add 10 percent to account for cuts and breakage.
