three-dimensional geometry

Three-dimensional geometry is the study of shapes and spaces that have depth, in addition to length and width. It involves understanding figures like cubes, spheres, and pyramids in 3D space. Unlike two-dimensional geometry, which deals with flat shapes like squares and circles, three-dimensional geometry helps us analyze the volume, surface area, and properties of objects we encounter in the real world. This understanding is crucial in fields such as architecture, engineering, and computer graphics, as it allows us to visualize and manipulate objects that occupy physical space.
