Perimeter is a concept which is relevant to closed 2-dimensional shapes, not 3 dimensional objects.
The difference is that two-dimensional shapes have a length and a width while three-dimensional shapes have a length, width, and depth. While some examples of two-dimensional shapes are circle, rectangle, and triangle, example of three-dimensional figures are a sphere, cuboid, and a pyramid.
Polygons !
You can't. Volume is only for 3 dimensional shapes. You won't find a way of using volume in any kind of 2 dimensional stuff.
The three dimensional figures are called Space figures
There are infinitely many different plane figures that can be made up of 2-dimensional shapes - provided that they are all in the same plane. There cannot be any 3-dimensional shapes involved.
They can be 2 dimensional shaped polygons or 3 dimensional shaped polyhedrons in algebraic geometry
Many shapes have curves. Some curved shapes include:circle (2-dimensional)cone (3-dimensional)sphere (3-dimensional)cylinder (3-dimensional)
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
You know how 2-dimensional shapes are flat right? Well 3-dimensional means that it can go to and from you also.

No because isosceles triangles are 2 dimensional shapes.
There are none because volume only relates to 3 dimensional shapes and not 2 dimensional shapes as in the question.
all regular polygons

Yes. Parallelograms are flat shapes (polygons). 3-dimensional forms are polyhedrons.
Normally perimeters are are only applicable to 2 dimensional shapes.
