8 sheets is needed to cover 255 square feet, 255/(4x8)=7 31/32. But the usage of the plywood isn't specified. If the plywood is for the walls, most rooms are 8 feet tall, so the perimeter is important. In that case, we can wildly guess that this is a 15x17 room, and that has a perimeter of 15+15+17+17 = 64. It would take 16 sheets to cover the walls of a 15x17 room.
