Note: The entity parameter stays 'this' since we want the block the entity is targetting. This can change based on the block the player has in their hand (see scaffholding). With a scaffhold in hand, the scaffhold blocks in the world become solid 1x1x1 cubes, and without they follow their model's shape.
