If we substitute and , we get , so that
which is independent of , which in turn means the surface can be treated like a surface of revolution.
Consider the function defined over . Revolve the curve described by about the line . The area of the surface obtained in this way is then

-12e-x + 8 = 7
-12e-x = 7-8
-12e-x = -1
12e-x = 1
e-x = 1/12
ln(e-x) = ln(1/12)
x = -ln(1/12)
x = -2.485
