Problem

Region R in the first quadrant is bounded above by the curve

y=5-x

and below by the curve

y=x

. Briefly describe, in one or two sentences, how the distance between these curves at a fixed

x

–value determines the side length of each square cross section that is perpendicular to the

x

–axis.
