A block has a finished surface that provides an attractive appearance. The block is relatively large in size, allowing the quick construction of a wall, such as a retaining wall, using the block. The block includes one or more lift devices embedded in the block that allow the block to be lifted using a suitable lifting apparatus, such as a crane, forklift, backhoe, etc. The block includes multiple retaining knobs that protrude from the lower surface of the block and help to align a block with previously-laid blocks underneath. The block includes multiple voids that extend from the top surface to the bottom surface of the block, and that align with each other when the blocks are stacked into a wall, thereby allowing fill material to be placed in the voids to strengthen the wall. The block is constructed using a block forming apparatus that includes one or more form panels that each have multiple form liners to provide a textured surface of the block. Each form panel may be pivoted away from a bottom surface of the block forming apparatus for easy removal of the block and for easy changing of the panels to fabricate blocks with different characteristics using the same block forming apparatus. The preferred embodiments also include methods for doing business, including the selling, leasing, and purchasing of the block forming apparatus for on-site fabrication of blocks.
