Which term describes the amount of space that a three-dimensional object occupies?

• A. Volume
• B. Mass
• C. Area
• D. Density

Answer: (A)

Volume describes the amount of space a three-dimensional object occupies. It is measured in cubic units, like cubic centimeters or liters, reflecting the space inside the object. For a regular-shaped solid, you find volume by multiplying its length, width, and height; for irregular shapes you can use water displacement to see how much space the object takes up. This concept is different from mass, which measures how much matter is in an object, and from area, which measures the two-dimensional surface on a shape. Density combines the two ideas as mass per unit volume. For example, a box that is 2 by 3 by 4 has a volume of 24 cubic units. Volume.
