In art terms, volume refers to form enclosing space.

• A. A space within a negative area.
• B. Form enclosing space.
• C. The outline of a shape.
• D. The texture of a surface.

Answer: (B)

Volume is the measure of the space a form occupies in three dimensions. It’s the space enclosed by the boundaries of the form, giving weight and solidity to objects in art. That’s why the description that volume is a form enclosing space fits best—a solid form has interior space defined by its surfaces. The other ideas don’t fit volume: a space within a negative area describes surrounding space rather than the form’s own interior; the outline of a shape is just a boundary in two dimensions, not the space inside; and the texture of a surface refers to feel or appearance, not how much space the form occupies.
