okay here is the difrence a cuboid is a shape that is 3D and has eight faces a cylinder however is a 3D shape but it only has 2 faces the top and the bottom face
A 3D shape with one curved face is a cylinder. It has a circular base and a curved surface that connects the two bases. The curved face wraps around the side, while the top and bottom faces are flat circles.
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
A solid
The simplest such shape is PYRAMID.

A rather simplistic answer is: A cube or cuboid shape has (usually) 2 sides, 2 ends, 1 top and 1 bottom.
A hexahedron has a triangular pyramid on top and on bottom and share the bases.

A hexahedron is the name for a 6 sided 3D shape.
A nonagon is a 2D shape and there is not a 3D equivalent shape.
the name of a 20 sided 3d shape is called a icosahedron

A 3D shape with one curved face is a cylinder. It has a circular base and a curved surface that connects the two bases. The curved face wraps around the side, while the top and bottom faces are flat circles.
If you take a regular four sided pyramid and chop off the top, parallel with the base, the left over piece would be a solid with four identical trapezoidal faces and a square top and bottom. The only name I know is 3-D trapezoid.
There is no special name since the resulting shape depends on the original shape. For example, a cuboid will remain a cuboid, a cube will become a cuboid.
