A three-dimensional object is any object with height, width and depth. The term "three-dimensional" is in reference to those three measurements. A solid object is another term for a three-dimensional object.
Continue ReadingIn the physical world, most objects, such as chairs, desks, trees and people, are three-dimensional. Even paper, which seems like it has only two dimensions, is actually three-dimensional, for it has a very small depth. In geometry, examples of three-dimensional objects include spheres, cylinders, cones, cubes and pyramids. These solid objects are plotted on a coordinate system with three axes: the x-axis, the y-axis and the z-axis. Two-dimensional objects, such as squares and circles, are plotted on a two axis system with only an x-axis and a y-axis.
