a cylinder ;)
a tetrahedron (aka three dimensional triangle)
A cube.

A cube is specifically a three-dimensional object in geometry and therefore cannot be two-dimensional.
A sphere is a round object. It has no sides. The object is 3-D. (Three Dimensional)
One - a rectangle is a flat shape - not a three dimensional object !
The flat surface of any three dimensional object is called a face; a prism is a three dimensional object.A tetrahedron has 4 faces, a cube has 6 faces, an octahedron has 8 faces, etc.
A cube is a three dimensional object with all faces squares. A cuboid is a three dimensional object with 4, or all 6, faces rectangles (and not square).
It is the total surface area.
When two faces of a three-dimensional object intersect. Take this two-dimensional symbol for example: ^ Imagine that that carrot symbol is actually three-dimensional. The vertex is your edge.
Two dimensional object is a plane figure where as three dimensional object is solid (space) figure.
A hexahedron. Cubes, cuboids, parallelepipeds are all examples.
