Uh-oh! Arlen needs your help. He is trying to write an integral for the volume of square cross-sections perpendicular to the -axis where the base is the region bounded by the -axis and on the interval . Help him set up this integral.

These cross sections are squares. Their area formula is well known.

The function and the bounds must be in terms of , because the cross sections are perpendicular to the -axis. So, rewrite the function in terms of and find the -values that correspond with the given domain.
