That depends on its application in science or geometry which has not been given. In science it can turn light into different colours and in geometry it can be in the form of a triangular prism.
It is called a cuboid.
It is simply called a pentagonal prism. That is a prism based on the 2D shape known as a pentagon.
It could be called a square prism but a more common name would be a cuboid.
A rectangular prism with 6 congruent faces is called a cube.
The device is called a prism. It refracts white light into its component colors by bending each color at a slightly different angle as it passes through the prism, resulting in a spectrum of colors being produced.

A prism refracts light into its component colours just like a rainbow does, so some of the colours are.... * Red * Orange * Yellow * Green * Blue * Indigo * Voilet .... and there are lots of intermediary colours in there also.
The device is a glass prism. A cross-section of a prism is an isosceles triangle.
refraction, do this by shining white light (all the colours) through a prism which then splits the wave lengths into sperate paths showing all the colours of white light. So white light has a specific frequency, shine it through a prism and you split the frequency up into smaller bits hence the colours of light.
A prism will split white light into its constituent colours (the colours of the rainbow). "White light" is the light we see around us i.e. natural light from the sun. This light is made up of all the colours in the visible spectrum
When white light passes through a prism, it is refracted and separated into its component colors, forming a spectrum from red, orange, yellow, green, blue, indigo, to violet (ROYGBIV). Each color has a specific wavelength and frequency.
A prism can be used to split light into its colors through a process called dispersion. When light enters the prism, it bends at different angles depending on its wavelength, causing the colors to separate based on their individual wavelengths.
It is split/dispersed further for exactly the same reasons as one prism splits white light. Isaac Newton's classic experiment conducted during the plague year of 1665 in England was arranged as follows He closed the wooden shutters in a room during a sunny day and made a hole in the shutters to allow a shaft of sunlight to enter the darkened room. On a pedestal in the centre of the room he arranged a glass prism to refract the white sunlight into a spectrum of colours which were displayed on the whitewashed wall. He then blocked all the other colours except red light emitted from the first prism by using a sheet of wood. The red light from the first prism was then directed towards a second glass prism to see if more colours or white light would be generated. He found that the red light was further refracted and no other colours were produced. He thus determined that sunlight was composed of the 7 colours of the spectrum. It is not at all easy to take a spectrum and recombine it through a prism to make white light. It can be done by mixing red,blue,and green light from separate pure light sources of these colours. This is how colour television works and is called additive mixing .This is different to mixing paint pigments together, this is called subtractive mixing.
White light is composed of many colours. When these colours combine, they look white. One way of showing that white light is composed of different colours is to make white light pass through a glass prism. This splits up the white light into its constituent colours. I f you hold a screen in its path, you will see a band of colours. This band of colours is called the spectrum. Since it is visible to human eyes, it is called the visible spectrum.
The spreading effect when light passes through a prism and separates into different colors is called dispersion. This occurs because different wavelengths of light are refracted by different amounts as they pass through the prism, causing them to spread out into a spectrum.
