Why are the flat surfaces on a rectangular prism called faces?

The flat surfaces** **on a rectangular prism are called faces because they form the exterior of the rectangular prism , and they are the only parts of the prism.
What is Three dimensional shape?
a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions —length, width, and height.
A rectangular prism is a polyhedron with two congruent and parallel bases.
Rectangular prism is also called a cuboid
The flat surfaces on a rectangular prism are called faces because they form the exterior of the rectangular prism, and they are the only parts of the prism that can be seen from the outside.
Each face has two dimensions (length and width) and all six faces together form the rectangular prism's shape.
Hence, the flat surfaces on a rectangular prism are called faces because they form the exterior of the rectangular prism, and they are the only parts of the prism.

The flat surfaces on a rectangular prism are called faces because they are 2-dimensional geometric primitives used to represent the exterior boundaries of a 3-dimensional shape. In geometry, a face refers to any of the flat surfaces that make up the boundary of a solid object. For instance, a cube, which is a type of rectangular prism, has six faces, each a square of the same size.
These faces are essential in defining the shape and structure of the prism, and they intersect at edges and vertices to form the entirety of the prism's shape. Faces can be seen in various geometrical shapes, where they span from simple squares and rectangles to complex polygons, depending on the nature of the 3-dimensional figure.
In irregular-shaped samples, such as single crystal samples that might exhibit facets corresponding to a range of different Miller Index planes, these flat surfaces still represent the outer limits of the object but may vary in their orientation and atomic structure. Yet, they serve the same purpose: defining the boundaries of the solid and its interaction with its environment, like light reflection forming mirror images on these smooth surfaces.

The flat surfaces on a rectangular prism are called faces because they form the external boundaries of the shape. Each face is a two-dimensional surface that contributes to the overall structure of the prism. A rectangular prism has six faces, with each face being a rectangle that defines the volume of the object.
