A cylinder has 2 flat, parallel faces.
Yes.
No, a prism cannot have curved sides. A prism is a polyhedron with two parallel and congruent polygonal bases connected by lateral faces that are parallelograms. The lateral faces of a prism are always flat, planar surfaces that are perpendicular to the bases. Curved sides would not meet the definition of a prism.
No, a sphere is not a prism. A prism is a polyhedron with two parallel and congruent faces called bases, and all other faces are parallelograms. A sphere, on the other hand, is a three-dimensional geometric shape with all points on its surface equidistant from its center, with no faces, edges, or vertices. In essence, a sphere is a curved surface while a prism is a polyhedron with flat faces.
All the faces of a triangular prism must be flat. So finding them should not be too difficult!
The flat surfaces on a pyramid are called faces. A pyramid has one base and triangular faces that meet at a single point called the apex. On a cube or rectangular prism, the flat surfaces are called faces as well. But unlike a pyramid, a cube has six square faces, while a rectangular prism has two rectangular bases and four rectangular faces.
A prism has no curved surfaces. It has 5 or more flat faces.
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
A cylinder has 2 opposite parallel flat faces
A flat square has 4 faces.
Faces
There are five of them.
