Step-by-step explanation:
We have,
Diameter of cylinder, d = 39.2 mm
Radius, r = 19.6 cm
Height of the cylinder, h = 39.2 mm
It is required to find the surface area of this cylinder. The formula of the surface area of cylinder is given by :

Putting all values we get :

 
        
             
        
        
        
9514 1404 393
Answer:
   486 square units
Step-by-step explanation:
Use the surface area formula with the given numbers.
   SA = 2(LW +H(L +W))
   SA = 2(12·6 +9.5(12 +6)) = 2(72 +9.5(18)) = 486
The surface area of the box is 486 square units.
