A cylinder
Yes a prism can have a square cross-section
The cross section of a figure is done by slicing part of the figure off a certain way. Inside the sliced area, there will be a 2-D figure. That 2-D figure is the cross section of the figure.
A cylinder has a circular cross section, a square prism has a square cross section.
Columns that square in cross section
The following are some shapes having a square cross section: a cube, a cuboid, a square pyramid.

a square
It can be a square, a trapezium, a quadrilateral or a triangle - depending on the inclination of the plane which defines the cross section.
Depending on the inclination of the plane used for the cross-section, it could be a square, rectangle, trapezium, triangle.
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.
When the 3-d shape is a prism and the cross section is in a plane at right angles to the length of the prism.
