What is Volume according to the provided material?

• A. The amount of 2-dimensional space.
• B. The amount of 3-dimensional space occupied by an object. Height times Length times Width.
• C. The mass of an object.
• D. The density of a substance.

Answer: (B)

Volume measures the three-dimensional space that an object occupies. It tells you how much space is inside a solid, not just its surface. For box-shaped objects, volume is found by multiplying the three dimensions: height times length times width. This gives the amount of space inside the object in cubic units (for example, cubic centimeters or cubic meters).

This isn't the same as area, which is only two-dimensional space on a surface. It isn't mass, which is how much matter an object has, nor density, which is how much mass per unit volume. So the description that defines volume as 3-dimensional space occupied by an object aligns with the concept being tested.
