6. We will have that if we rotated the rectangle and then determined the cross-section shape, the volume would be given by the following expression:
[tex]V=l\cdot w\cdot l\Rightarrow A=l^2\cdot w[/tex]Now, we replace the values:
[tex]V=(18)^2\cdot(10)\Rightarrow V=3240[/tex]So, the volume of the shape delimited by the cross-section would be 3240 cubic inches.
