A prism has no curved surfaces.
It has 5 or more flat faces.
A cuboid has 6 flat faces but no curved surfaces. ..________ ./............../| /_______/.| |..............|.| |..............|./ |_______|/
A pentagonal prism has 2 pentagonal bases and 5 rectangular lateral faces. The rectangular faces are the only curved surfaces in this context, as the term "curved faces" typically refers to surfaces that are not flat. Therefore, a pentagonal prism has 0 curved faces, as all its faces are flat.
A cylinder has 2 equal parallel flat surface circular bases and a curved surface body.
Just one at the base, the rest is a curved surface
A cone has one flat surface, which is its circular base. The curved surface that extends from the base to the apex is not flat. Therefore, in total, a cone has one flat surface.
A triangular prism contains zero curved and 5 flat surfaces.
A cuboid has 6 flat faces but no curved surfaces. ..________ ./............../| /_______/.| |..............|.| |..............|./ |_______|/
A pentagonal prism has 2 pentagonal bases and 5 rectangular lateral faces. The rectangular faces are the only curved surfaces in this context, as the term "curved faces" typically refers to surfaces that are not flat. Therefore, a pentagonal prism has 0 curved faces, as all its faces are flat.
None.
Two flat faces (one at either end of the prism), and a curved side.
A cylinder has 2 equal parallel flat surface circular bases and a curved surface body.
Just one at the base, the rest is a curved surface
It has no CURVED faces.
A cone has one flat surface, which is its circular base. The curved surface that extends from the base to the apex is not flat. Therefore, in total, a cone has one flat surface.
A rectangular prism is a cuboid. It has no curved faces.
It has no CURVED faces.
A hexagonal pyramid has one curved surface, which is the lateral surface that connects the apex to the base. The base of the pyramid is a hexagon, contributing six flat surfaces. Therefore, in total, the hexagonal pyramid has one curved surface and six flat surfaces.
