Answer:

Step-by-step explanation:
Let the side length of the square base =s feet
Let the height of the box = h
Given that the volume of the box = 
Volume of the box =
Then:

Surface Area of a Rectangular Prism =2(lb+bh+lh)
Since we have a square base, l=b=s feet
Therefore:
Surface Area of our closed box

Answer:
x = -11
Step-by-step explanation:
7x-8 = 14+9x
7x - 8 - 7x -14 = 14 + 9x -7x -14
-22 = 2x
x = -11
I think it's less than 7/2 usually bigger numbers are less in this case.
sorry if you got that wrong but i'm 85% sure
