A cylinder has 2 flat surfaces and 1 curved surface.In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. As such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinderrespectively; these have no flat surfaces.
A triangular prism contains zero curved and 5 flat surfaces.

Two. The ends.
It has a flat base, a curved surface area, a circular edge and one vertex.
Flat surfaces: 6Curved surfaces: 0.
It has three shapes. Two surfaces are flat circles and one is a curved rectangle.
2 flat surfaces unless it is rolled up in which case it has 2 curved surfaces.
