They are called prisms.
Prisms are used in binoculars to bend and reflect light, allowing the viewer to see a magnified image. Binoculars typically use either Porro prisms or roof prisms to achieve this.
There are many types of prisms such as rectangular prisms,polyganic prisms crossed prisms and etc.
Cylinders and cuboids are types of prisms.
Prisms (not prism's) got their (not there) name from the Greek prisma, meaning sawed.
Triangler Prisms are like chocolate bars
This is because there is no limit on rectangualar prisms and most boxes can hold cube or rectangular prisms not triangular pyrimids or prisms or hexagonal prisms.
Prisms are objects that divide the colours of the rainbow. Some prisms are Triangular, Rectangular and etc.
NO, but prisms are polyhedra. Polyhedra include a lot more shapes than just prisms.
