In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point.
The meaning of THREE-DIMENSIONAL is of, relating to, or having three dimensions. How to use three-dimensional in a sentence.
Just like two-dimensional vectors, three-dimensional vectors are quantities with both magnitude and direction, and they are represented by directed line segments (arrows). With a three-dimensional vector, we use a three-dimensional arrow.
In geometry, a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions— length, width, and height. Unlike two dimensional shapes, three-dimensional shapes have height, which is the same as thickness or depth.

These shapes exist in three dimensions: length, width, and height. This article aims to cover definitions, types, formulas to calculate their volume and surface area, real-life applications, and examples to better understand this topic. What is a 3 dimensional shape?
Unlike flat two-dimensional shapes (e.g. circles, triangles, squares, etc.), a 3D shape has volume and has a physical presence in three-dimensional space. 3D shapes can be observed from different angles and perspectives and they serve as the building blocks of the real world.
THREE-DIMENSIONAL definition: 1. having or appearing to have three dimensions (= length, width, and height) and therefore looking…. Learn more.
A three-dimensional figure or object is a solid that occupies space in our physical environment. Every three-dimensional figure has length, width, and height. Unlike two-dimensional objects, three-dimensional figures have an additional property: their height is also known as depth.
