z = height
y = depth
x = width

.
, total surface area.

Sensing advantage in having volume formula all in one variable, x, the transformed surface area formula should be solved for y.

----Actual will use this form
----But could use either of these forms once x is found.

VOLUME,

Treating v as a calculus problem, ,

Where is this equal 0?

------Using this value of x, calculate for y and z.
