The amount of space an object takes up is called

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

Answer: (B)

Volume is the amount of space an object occupies. It tells you how much room something takes up, and it’s measured in units like cubic centimeters (cm^3) for solids or liters (L) and milliliters (mL) for liquids. For regular-shaped objects you can find volume with formulas (for example, a rectangular block is length × width × height). For irregular objects, you can use water displacement to see how much water is moved, which equals the object's volume.

Among the terms listed, volume fits the definition of space occupied. Mass is about how much matter there is, not how much space it takes up. Density is mass per unit volume, tying together mass and space but not describing space by itself. Matter refers to anything that has mass and takes up space, but that’s the substance of objects, not specifically the amount of space they occupy.
