Final answer:
a) solid.
The planar sculpting technique helps create sculptures that vary in shape, often with flat faces or planes. These sculptures feature sharp edges and flat areas, which emphasize the definition of the three-dimensional form.
Step-by-step explanation:
The planar sculpting technique is often used to create forms that vary in shape. Unlike forms that are solid or uniform, planar sculpting allows for a sculptural form that has flat faces or planes, which can be angled in various ways to capture light and create shadows. Sculptures made with planar sculpting can portray complex geometric forms, abstract shapes, or fragmented figures. The technique emphasizes the sharp edges and flat areas to define the three-dimensional object.
When it comes to growth or shrinkage in relation to length, the context would typically be different, as planar sculpting does not relate to growth patterns but rather to the aesthetic and structural characteristics of the sculpture itself.
