They are closed 2-D shapes with straight sides.
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
a cube has parallel faces so does a cuboid and so does a cylinder and also if you want to find out lots more stuff about 3-D shapes or 2-D shapes see the website in the related link
There is Paper or Card or some other art stuff you have in your home
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width

yes
No because isosceles triangles are 2 dimensional shapes.
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
No, they have only one face.
2d shape is a dimension
