Octagonal Prism
Hexagonal Prism.
Its a rectangular prism
A cuboid can have 6 rectangular faces, 12 edges and 8 vertices
The question is somewhat confused. It has "... 6 flat SQUARE faces 2 are SQUARE and 4 are RECTANGLES ...." Assuming the first part is wrong, the shape is a cuboid.
An octahedron shape is one which has 8 faces. Since it is a prism it must be a hexagonal prism (2 hexagons and 6 rectangles = 8 faces). And a hexagonal prism has 2*6 = 12 vertices.
A polyhedron with rectangular bases and parallelogram faces is known as a rectangular prism, or cuboid. In this shape, the two opposite faces are rectangles, while the remaining four faces are parallelograms, specifically rectangles in the case of right rectangular prisms. This polyhedron has 6 faces, 12 edges, and 8 vertices.
The three-dimensional shape that has 2 octagons and 8 rectangles is called a truncated octagonal prism. A truncated octagonal prism is a polyhedron with 10 faces, including 2 octagonal faces and 8 rectangular faces. The octagonal faces are the bases of the prism, while the rectangular faces are the lateral faces that connect the bases.
A rectangular prism has 6 sides and 8 vertices.
Since it has 10 faces, it must be a decahedron.
A cuboid could fit the given description
It is a cuboid that has 8 vertices, 12 edges and 6 faces
It is a cuboid that has 8 vertices, 12 edges and 6 faces
