Each cross section is a square with side length equal to the vertical distance between the curves 
and 
, with 
, or 
. Then each section has an area of 
, so the volume of this solid is
For computing the integral, consider the substitution
Then the integral becomes
Integrate by parts twice; for the first round, take
For the second round, take
and the rest is trivial.
Answer:
incorrect this is negative five over zero.
