Which term describes an object's maximum dimensions in the X, Y, and Z axes?

• A. Faces
• B. Extents
• C. Polygons
• D. Grids

Answer: (B)

In 3D modeling, the term that describes how big an object is along each axis is extents. It’s the span from the object's minimum coordinates to its maximum coordinates on X, Y, and Z, effectively the size of its bounding box in those directions. Knowing extents gives you three measurements—width, height, and depth—so you can place, scale, or collide objects accurately. The other terms refer to parts of the geometry or layout rather than overall size: faces are the flat surfaces, polygons are the individual faces, and grids are structural or reference patterns. Extents directly captures the maximum dimensions along the three axes.
