a prism
Prism
length = volume/cross-section
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
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.
The formula for cross section area of a square is very easy to use. Measure the length of one side of the square it. If you are doing the cross section area of a rectangle, measure both sides and multiply them together.

An object with the same cross-section for its whole length is called a prism.

Make the length shorter; make the cross section bigger; choose a material with a low resistivity.Make the length shorter; make the cross section bigger; choose a material with a low resistivity.Make the length shorter; make the cross section bigger; choose a material with a low resistivity.Make the length shorter; make the cross section bigger; choose a material with a low resistivity.
A rectangular prism has the same cross section throughout its length, a pyramid doesn't however
The following are some shapes having a square cross section: a cube, a cuboid, a square pyramid.
Volume = area of cross-section*length
Ellipse * * * * * At right angles to the length, it would be a circle. Along the length it would be a rectangle. Only a diagonal cross section would be an ellipse.
