This is an impossibility. If it is a solid figure then it will have more than 1 surface. If it has only 1surface and it is a solid, then it must be a sphere, but the surface of a sphere is not flat is it? By using the word 'solid' then by definition, it is three dimensional and has thickness. A cylinder has no vertices , but it has 2flat surfaces. A vertex is a point where three lines meet, such as on a pyramid, which has 4 vertices. Have I forgotten something or is this a 'trick' question?
The only regular solid with a single flat surface is a sphere.
(A Mobius strip also comes to mind.)
It is called a face.

The crust is the solid surface of the Earth.
What figure has 6 flat surfaces that all look exactly the same
A flat surface of a solid is usually the face of the solid. +++ Also sometimes called a "facet", particularly on solids having very many flat faces.
They distort the surface because they are flat, while the surface is not.

A a solid figure on a flat surface is a plane figure (I do believe)
If you mean 1 flat surface and 1 vertex, then the only thing I can think of is a cone.
the flat surfaces of a solid figure are the
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.
A face is the flat surface on a solid figure. For example, a triangular prism has five flat surfaces and therefore five faces.
