A parallellopiped
Its an eqaulateral tringle
it is a 3D shape with 8 faces 8 edges and 6 vertices if you want a picture of it type in pcures of 3D diamonds.
only if it is in a certain shape, although the 3d shape would not look exactly like the 2d one, take this, if a square were to be turned into a square, it would have to be extended, but if you were to do this it would just stay as a 2d square, in a 3d world, but if it were a net (like the t cube) then yes, it would be able to become 3d
Many 3d shapes have a corner.

A cut diamond is a 3D object as it has length, width and depth (even if it is roundish like a pebble)
A diamond is a 3D shape, specifically a type of polyhedron known as a rhombus. A rhombus is a quadrilateral with all sides of equal length, opposite sides parallel, and opposite angles equal. In a three-dimensional space, a diamond shape is a polyhedron with four faces that are congruent rhombi.
By definition a sphere is 3D. If it were only 2D it would be a circle.
a rectangle in 3D A brick shape.
A rhombus is a four sided polygon, a quadrilateral. It is a 2d shape. 2d shapes have 2 dimensions, like length and width. 3d shapes have 3 dimensions, like length, width and depth.
Yes but the correct term is octohedron
A parallelogram in 3D looks like a flat, four-sided shape where opposite sides are parallel. It can appear as a slanted rectangle or a diamond shape depending on the orientation of the sides. The angles between the sides can be acute, obtuse, or right angles.
It looks like a 3D shape that has 9 sides (the cousin of an octogon).

A box - for example a box of cereal
A 2D shape is flat and only has a surface area whereas a 3D shape is an object that has surface area and volume.
