The surface area of the box will be 112 in²
Explanation
According to the given diagram, the shape of the box is Right Rectangular prism.
The formula for the surface area is :
, where 
length, 
width and 
height of the rectangular prism
Given in the diagram that, 
So, plugging the values into the formula...
So, the surface area of the box is 112 in²
Imagine to have three segment: 1 is x, another is x+7 and the last is x-5. You know that their sum is 50, so you can write:
x+(x+7)+(x-5)=50
simplify:
3x+7-5=50
3x=48
x=16
16+7=23
16-5=11
So the thee sides are 11, 16 and 23.
Hope this helped.
X/2 - 6 = 15
x/2 -6 +6 = 15 + 6
x/2 = 21
x/2 × 2 = 21 × 2
x = 42
Check
42 ÷ 2 - 6 = 15
42 ÷ 2 = 21 -6 = 15
