a cone because if u "squash" it it will give you flat faces and it can roll because its smooth.
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.
It has one flat face if its 2 dimensional. It has 6 flat faces if it is 3 dimensional.
A contradiction. A solid is a 3-dimensional object, a face is 2-dimensional. Hence you cannot have a solid face.
cylinder
..... 2 opposite parallel flat faces
A cylinder would fit the given description.

cylinder
A cone?
3d shape* * * * *It does not.A face is a plane (2-dimensional) part of the surface of a solid (3-dimnsional) object. Sometimes the term is includes curved surfaces, such as along the length of a cylinder.
A Cylinder
cylinder
..... 2 opposite parallel flat faces
It has 2 because it has a curved face and a flat based face
A "hemisphere" - a ball that's been cut into 2 equal parts. i.e "half a sphere".
