What represents mass in artwork or sculpture?

Mass in artwork or sculpture refers to the perceived weight, density, and three-dimensionality of an object. It encompasses the physical and visual qualities that contribute to the work’s overall solidity and presence within space.

Volume is essential for representing mass because it defines the amount of space an object occupies and how it interacts with light and shadow. In sculpture or three-dimensional artwork, volume can create a sense of bulk and, in turn, convey the concept of mass. When a sculpture has a large volume, it can appear heavy and substantial, contributing to the viewer's perception of its mass.

Other options like shape, contour, and form are related concepts. Shape relates to the two-dimensional aspect of an object, contour describes the outline or surface characteristics, and form encompasses the overall structure and arrangement of elements in a piece. While these terms can contribute to the overall perception of mass, volume specifically addresses the space occupied by the object, making it the most accurate representation of mass in artwork or sculpture.
