a 3d object is a object that isn't flat. for instance, a square in 3d form would be a cube
Well, a 2D object has only length and width, but a 3D object has length, width, and depth.
a 2D object is is flat and on the other hand a 3D object is bulgy
Paper is a 3D object.
on a 3D object to find the surface is to look on all flat surfaces. yourwelcome
A sphere.
Um... What?
Maybe a circle and a triangle, and indeed a straight line are not 3D.
It is the volume of the object.

A Heptagon is a 3d object with 7 faces. An example of a heptagon is a hexagonal pyramid (that is a pyramid with a hexagon for the base).
Unless it is a 3-d net (an object made up only of lines in 3D space), all 3D objects will take up space.
What is 3D printing?3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created.Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.How does 3D printing work?It all starts with making a virtual design of the object you want to create. This virtual design is for instance a CAD (Computer Aided Design) file. This CAD file is created using a 3D modeling application or with a 3D scanner (to copy an existing object). A 3D scanner can make a 3D digital copy of an object.3D scanners3D modeling softwareFor more info how 3d printing works head over to : 3D Printing Basics | FAQ | Beginner's guideUpvote
