A face is a flat surface that forms part of the boundary of a three-dimensional object such as a cube or pyramid. It is defined by its edges and vertices.
In mathematics, a face is a two-dimensional figure that is a part of a three-dimensional solid. It is one of the flat surfaces that make up the solid shape. For example, if you consider a cube, each of its six sides is a face. Faces are often polygons, such as triangles, rectangles, or pentagons, but they can also be other shapes. Faces play an important role in defining the shape and structure of three-dimensional objects.
