Answer:
the answer is 19.3137
Step-by-step explanation:
each of the diagonal lines are 2.84 so multiply that times 4 because there are 4 of them then add the top and bottom lines which are 4 each so 8 plus the diagonal lines which are 11.3137 and you get 19.3137.

Answer:
S(x) = x² + 390224/x
Step-by-step explanation:
Volume of the open box = V = 97556 cm³
Material needed:
Let´s call x the side of the square base then the area of the base is
A(b) = x²
For the sides of the box, we have 4 sides each one with area of x*h
where h is the height of the box
The volume of the box V(b) = 97556 = x²*h then h = 97556/x²
S(x,h) = x² + 4*x*h*
The surface area of the box as function of x is:
S(x) = x² + 4*x*97556/x²
S(x) = x² + 390224/x
