Question 344411
Let x be the lenth of a side of the base
{{{volume = 2m^(3)= x^(2)*h}}} (V=lwh for a rectangular solid)
h=2m/x^2
Surface Area in general for a rectangular solid is:
2lw+2lh+2wh
Your question states this is an "open" rectangular Box with square base:
Thus: surface Area for the open box would be:
A= x*x+2x(h)+2x(h) 
Substitute for h
