That is the definition of the surface area!
(surface area of cube 1 or 2 (either)) times 2 = (total surface area of two identical cubes)
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
total curved surface area = 2*pie*r^2
The total surface area increases.
