So, there are 4 solutions.
 
        
             
        
        
        
Oh, this is easy. For any prism, you find the surface area by finding the are of all the sides. I will post all surface area formulas here, for reference
Cube:
Surface area = 6 × a2
Right circular cylinder:
Surface area = 2 × pi × r2   +  2 × pi × r × h
pi = 3.14
h is the height
r is the radius
Rectangular prism:
Surface area = 2 × l × w  +  2 × l × h  +  2 × w × h 
l is the length
w is the width
h is the height
Sphere:
Surface area = 4 × pi × r2 
pi = 3.14
r is the radius
Right circular cone:
Surface area = pi × r2  +  pi × r ×( √(h2 + r2)) 
pi = 3.14
r is the radius
h is the height
l is the slant height 
Right square pyramid:
Surface area = s2 + 2 × s × l
s is the length of the base
h is the height
l is the slant height
