a cylinder
A cube is a 3d square. A sphere is a 3d circle. A prism is a 3d rectangle.
A rectangle.
Because a rectangle is not three-dimensional it does not contain a volume but an area. A geometrical figure that is more efficient than a rectangle for area is a circle.
Draw a rectangle for the side of the cylinder and on top and bottom of this rectangle 2 circles for the base and the top of the cylinder The rectangle width would be the diameter of the circle large and the same height that the cylinder
A square or a rectangle is a 2-dimensional figure. It can have no mass.
A figure that has length and width but not height (ie, a plane figure such as rectangle or circle)
The cross section of a circle is a circle. A circle is defined as a plane figure (i.e. 2 dimensional object) with a constant radius in both dimensions. Since a cross section is, by definition 2 dimensional, a circle's cross section is the circle itself.

Rectangle is a two-dimensional figure.
Since a frustum is a portion of a solid, three-dimensional figure, and a rectangle is a plane, two-dimensional figure, there can be no such thing as the frustum of a rectangle.
