Two. One which is flat and the other which is curved.

Two flat and one 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.
This shape has 2 opposite identical faces and some other which are parallelograms is a prism. A cylinder shape has 2 circular faces and one curved face.

A cylinder, a semi-torus (half a doughnut).
a sphere :)
