A sphere a cube and a thin circular plate all of same material having same mass are initially heated to 200^(@)C . Which of these will cool fastest?

Statement- 1 : A sphere, a cube and a thin circular plate made of same material and of same mass are initially heated to 200^(@)C ,the plate will cool at fastest rate. Statement- 2 : Rate of cooling = (rhoAsigma)/(ms)(T^(4) - T_(0)^(4))alpha "surface area" . Surface area is maximum for circularplate.
