Assuming all of the bodies have same densities, the one which has largest surface area would cool fastest. By Newton`s law of cooling, heat transfer rate is directly proportional to 1) Temperature difference between body and surrounding.2) Surface area of body through which heat can transferred to the surrounding.So by this logic, plate would have largest surface area among others for the same volume ( same mass, same density). And hence it will cool faster than the others.
