A shape with 12 edges of the same length is a regular dodecahedron. This three-dimensional polyhedron consists of 12 regular pentagonal faces, with three edges meeting at each vertex. The regular dodecahedron is one of the five Platonic solids, characterized by its symmetrical properties and uniform edge lengths.
all of the shape, surface area is the total length of all edges of the shape
A shape that has equal dimensions of length, width, and height is called a cube. In a cube, all six faces are squares of the same size, and all edges are of equal length. This geometric shape is a three-dimensional figure often found in various contexts, including mathematics and real-world objects.
yes
Perimeter is the outside. The area is the inside of a shape.
A shape that has the same dimensions of length, height, and width is a cube. All its sides are equal in length, making it a three-dimensional geometric figure with six square faces. Each angle in a cube is a right angle, and it has a total of eight vertices and twelve edges.
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.
A polygon with all sides and all angles equal.
