Question 1024986
Base surface but not a top surface.  You have volume of 1 unit of whatever this volume unit may be, as V=1.


The dimension for height may be any variable you choose.  Try assigning y for the height.
{{{V=x*x*y}}}
{{{x^2*y=1}}}
{{{y=1/x^2}}}---------still two unknown variables, x and y.


The question to answer is, what is the expression for the surface area?
Four of the surfaces each are {{{xy}}}, and the base area is {{{x^2}}}.
-
The surface area for this box is  {{{4xy+x^2}}}.  You already know something about y, so you can substitute for y:
{{{4x(1/x^2)+x^2}}}
{{{4/x+x^2}}}
but since you are asked for all power functions of x, express this area as {{{highlight(4*x^-1+x^2)}}}.
