What term is used to describe a shape that can be created by forming two or more shapes or as a 3D shape?

The term "form" is accurately described as it pertains to a 3D shape or an object that can be created by combining two or more shapes. In the context of art and design, form refers to the physical volume and structure of an object, which is typically three-dimensional. This includes not only the outer characteristics of an object but also elements like texture and depth that give it a fuller representation in space.

While "shape" refers to the two-dimensional outline or configuration of an object, and "line" signifies a one-dimensional mark made by a moving point, "form" expands on these concepts by integrating these shapes into a three-dimensional context. "Value," on the other hand, refers to the lightness or darkness of a color, contributing to the overall perception but not directly to the creation of multidimensional structures. Thus, "form" is the most suitable term for describing how multiple shapes can be combined into a comprehensive 3D structure.
