Given that a typical cross-section of a solid taken perpendicular to the x-axis has an area of , set-up an integral to calculate the volume of this solid from []. Does it matter what the shape of the solid is? Explain.

Of course every shape has a different area function, and this area function .
It is not possible to know what the cross-sections looks like. Perhaps they are rectangles with height and base ? But they could also be strange looking shapes. Just as long as all of their areas (coefficient)(base)(height) , the Volume by Cross Section formula will work.
