What is the term for a figure that has height, width, and depth?

A figure that has height, width, and depth is referred to as three-dimensional. This means it occupies space and can be perceived from multiple angles, offering a sense of form and volume. Common examples of three-dimensional figures include cubes, spheres, and pyramids.

In contrast, a two-dimensional figure only has height and width without depth, existing only on a flat plane. It cannot be rotated or viewed from different angles in the same way a three-dimensional object can. One-dimensional objects possess only one measurement, either just length or height, making them even less complex than two-dimensional shapes. Flat shapes relate closely to two-dimensional figures, but do not encapsulate the concept of depth that is essential to three-dimensional figures. Therefore, three-dimensional specifically describes shapes that encompass all three spatial dimensions, distinctly identifying them from the other terms provided.
