all of the shape, surface area is the total length of all edges of the shape
yes
Perimeter is the outside. The area is the inside of a shape.
It is a cuboid or a cube
no
must all edges of semiregular polyhedron be the same length
If you mean 6 faces and 12 edges then a cube would fit the given description which also has 8 vertices.
An irregular polyhedron is a solid shape in which either all edges are not the same length, or all faces are not congruent polygons or all [solid] angles are not of the same measure.

A cube
They all have to be if it is a perfect cube.
yes
A cube is a three dimensional figure with all edges having the same length and all six sideshaving the same area. The length of a cube is the length of any edge of the cube; all edges having thesame length.
Perimeter is the outside. The area is the inside of a shape.
A polygon with all sides and all angles equal.
