8-111.

The base of a solid with square cross-sections perpendicular to the x-axis is bounded by f(x) = and the x-axis. Sketch the solid formed and set up an integral to find the volume from 0 ≤ x ≤ 4. Homework Help ✎

The base and height of each cross section will be the length of f(x) starting at x = 0 (an impossibly small square) and ending at x = 4 (a 2 x 2 square).
