A face is a flat surface. The only solid with no flat surfaces is a sphere.
It has two flat surfaces.
-- You can only do one solid figure at a time. -- Pick one solid figure to work on. -- Stare at it for a while. In your mind, look at all of its flat faces, even the ones you can't see in the picture. -- One at a time, write down the area of each flat face. -- When you have them all, add up all the areas of the flat faces. -- The sum of all the faces is the area of the whole solid figure. If you're doing this in the second grade, then you must be pretty smart. I'm proud of you.
a closed, flat figure is a polygon. But it is only a polygon when it is not round.
yes it does.
A cylinder
A rectangular prism.
a plane
cube There are a great many solid shapes that have only flat surfaces.
A face is a flat surface. The only solid with no flat surfaces is a sphere.
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?
Venus and Mercury also have solid surfaces.

Shapes have flat surfaces in plane geometry. They can also be described as two dimensional shapes.
