Soda can or cylinder
A cylinder.
The top and bottom flat surfaces (the 2 circles or ellipses) and the curved surface make up the 3 surfaces.
The cylinder only has 2 faces which are flat but the sides are curved.
When you say "What face" did you mean "What solid" has one curved face and two other flat faces? A solid that can be imagined is a melon wedge, cut from a sphere. Two flat faces come from the two cuts with a knife, and the one curved face that formed the rind. If you did not mean "What solid" then that makes your question unclear. I cannot imagine a face made from three other faces. Perhaps a face made from three other lines with one of them curved? It would seem you used a word wrong somewhere in your original question.
Soda can or cylinder
It has three shapes. Two surfaces are flat circles and one is a curved rectangle.

A cube has 6 flat faces

That's a Sphere not Cylinder cuz it had flat Circles Above and
A face, of a solid object, is a flat surface. If it is curved it is called a curved surface though sometimes it is also referred to as a face. Two faces meet at an edge, which is a line which may be straight or curved. Three or more faces meet at a point which is a vertex.
A cuboid has 6 flat faces but no curved surfaces. ..________ ./............../| /_______/.| |..............|.| |..............|./ |_______|/
A prism has no curved surfaces. It has 5 or more flat faces.
A sphere has no flat face and no vertices. It does have a curved surface; so it depends upon your definition of a face.
