Answer: 2 inch dimension will give smallest increase. 
Step-by-step explanation:
Length = 3 in 
width = 2 in
height = 6 in
Extra cardboard  means to find surface area 
on doubling the length 
length = 6 In
width = 2 In 
Height = 6In
Surface area for the above dimensions = 2 [ 6x2+2x6+6x6] = 120 sq in 
On doubling the width
length = 3 in 
width = 4 in 
Height = 6 inch 
Surface area for the above dimensions= 2 [ 3x4+4x6+6x3] = 2[54] = 108 sq inches 
On doubling height
Length =3 in 
width = 2 in 
Height = 12 in 
Surface area for above dimensions = 2 [ 3x2+2x12+12x3] = 2[6+24+36] = 132 sq inch
On doubling width surface area is minimum. 
 
        
             
        
        
        
Answer:
 answer of this qn is 15in^2
 
        
             
        
        
        
your equation would be 12/35x 
12/35 times 30/1 = 360/35 = 10 10/35 = 10 2/7 feet
hope that helps
