How do you find the volume of the solid with base region bounded by the curve #y=e^x#, #y=ln4#, and the #y#-axis if cross sections perpendicular to the #y#-axis are squares?
Since its cross-sections are squares, its area can be expressed as
So, the volume of the solid can be found by:
Can you go from here? You might have to use integration by parts twice.
