The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.

Volume in cubic feet = cross-section area*length
length = volume/cross-section
A cylinder has a circular cross section, a rectangular prism has a rectangular cross section.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
It depends on the inclination of the line of cross section. If it is at an incline to the sides and diagonal, the cross section is a point which becomes a line that increases in length, reaches a maximum, remains at that length and then shrinks back to a point. If it is parallel to a diagonal, the cross section is a point which becomes a line that increases in length, reaches a maximum and then shrinks back to a point. If it is parallel to a side, the cross section is a line of constant length.
