(4/3)*pi*r^3 = 288*pi
r= 6 units.
Therefore Surface area of the sphere is
4*pi*r^2 = 452.39 cubic units. ------- 1
Also since the chocolate was not wasted when it was molded in to a cube both the volumes of the now formed cube and the sphere should be equal. Therefore
s= 9.67 units.
Therefore it's surface area is
6×s^2 = 6×9.67^2 = 561.28 cu units.---- 2
From 1 and 2 we can say that cube has higher surface area for the same volume as that of the equivalent sphere.
