Volume Calculation of a Solid with Square Cross Sections

The video tutorial explains how to find the volume of a solid with a base region S, where cross sections perpendicular to the x-axis are squares. It begins by introducing the functions f and g, and discusses their behavior. The tutorial then focuses on determining the bounds of region S by finding where the functions are equal. Using a calculator solver, the x value is determined. Finally, the video demonstrates how to calculate the volume of the solid using integrals, considering the cross-sectional area as squares.
