Are you a math student? Then you should learn more about prisms, especially a rectangular prisms (It can also be called a cuboid) and what makes it unique. Basically, there are several important rules that identify a 3-dimensional shape of any prism.

It’s all about a six-sided object that is very familiar with all people, a simple box. You can also take into account a shoebox, a brick, and other similar objects to get a better idea of what a rectangular prism is.
