Volume is defined as which of the following?

• A. The surface area of a 3D object.
• B. The amount of 3-dimensional space occupied by an object.
• C. The height times width of a 2D shape.
• D. The diameter of a sphere.

Answer: (B)

Volume is the amount of three-dimensional space an object occupies. This is why we measure it in cubic units (like cubic centimeters or cubic meters): it quantifies how much space exists inside the object's boundaries. Surface area, by contrast, is about the exterior boundary and uses square units. A height times a width calculation gives area for a 2D shape, not volume, since a 2D shape has no depth. The diameter of a sphere is a linear measurement, a single length across the sphere, and does not describe how much space is inside.
