Which statement is true about milliliters and cubic centimeters?

• A. A milliliter is equivalent to a cubic centimeter
• B. A milliliter is twice a cubic centimeter
• C. A cubic centimeter is ten milliliters
• D. A cubic centimeter is one liter

Answer: (A)

Volume units in the metric system are the same amount of space, just written differently. A milliliter is defined as the volume of a cube 1 centimeter on each side, which is 1 cubic centimeter. So 1 mL equals 1 cm^3, making them interchangeable for measuring volume. In practice, you’ll see liquid doses given in milliliters, but the numeric value carries over directly if you think in cubic centimeters. For example, 5 mL equals 5 cm^3, and 1000 mL equals 1 L, which also equals 1000 cm^3 because 1 cm^3 equals 1 mL. The other statements would imply different relationships (twice as much, ten times as much, or a liter for cm^3), which isn’t correct.
