Where does the main character hide the body? in The Tell-Tale Heart

The main character in the Tell-Tale Heart hides the old man's body by dismembering it and putting it under the floorboards. He cuts off the head, arms, and legs, and uses a tub to catch the old man's blood so that he doesn't leave any evidence of his murder. He then tears up three of the floorboards and stores the body beneath them. When authorities arrive, he then sits on a chair on top of the loose floorboards, until he hallucinates the old man's heart beating and confesses.
