A prism has the same cross section throughout its length no matter what form it may take i.e. a cubic prism, a cuboid prism, a triangular prism, a hexagonal prism, a cylindrical prism etc.
There can be a heptagonal prism or an octagonal prism, but there is no such thing as a hectagonal prism.

A pentagonal prism has 10 vertices. A rectangular prism has 8 vertices. Therefore, a pentagonal prism has 2 more vertices than a rectangular prism.
difference between ordinary prism and constant deviation prism

It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
An ordinary prism disperses light based on varying angles of refraction, resulting in different colors being separated at different angles. A constant deviation prism disperses light in such a way that all colors are dispersed at a constant angle, maintaining a consistent level of separation irrespective of wavelength.
In surveying, it refers to the offset of the centre of the prism to the reflective section and the adjustment required to achieve an accurate reading. Each variant of prisms has its own independent prism constant that must accounted for when taking readings.
They both have sides that are rectangular in shape. They both have a constant cross-sectional shape equal to the shape of the ends (triangle for a triangular prism; rectangle for a rectangular prism).

By definition, the circular cross-section of a cone changes linearly in width as you go along its axis. By definition, the cross-section of a prism is constant along its axis. So, by definition, a cone prism is an impossible shape.
prism
The cross section of a pyramid shrinks from the shape of the base down to a point as you move along its axis from the base to the apex. The cross section of a prism is constant along its axis.
Prisms and gratings have different dispersive properties. Grating has a linear dispersion of wavelengths meaning the band on the focal plane varies linearly with the wavelength. Prisms are not linear, the shorter the wavelength the greater the dispersion. Thus, when a spectrum is being scanned, the dispersive device needs to rotates different amounts depending on whether it is prism or grating to focus light on the exit slit. If its grating, the slit width will need to be varied minimally; if it is a prism, the slit width will need larger changes as the dispersion gets greater.
