I hope this answers your question !

Answer 2

The surface of a solid is called its Face.

• Face in solid geometry is a flat surface which is a planar region that forms part of the boundary of a solid object and has a three-dimensional solid bounded entirely by faces is a polyhedron.

• The flat surface is known as the face of the solid and when two solids meet they form an edge. Similarly, when two Edges meet, they form a point. Hence, we can conclude that the flat surface which is present on any solid is referred to as a face.

• Every solid figure except a sphere has one or more flat surfaces called faces.
