Question

when measuring volume of a liquid, 1 ml is equal to
1 cm³
1 l
1 cm
1 m³

Explanation:

To determine what 1 mL equals, we recall volume unit conversions. 1 milliliter (mL) is a unit of liquid volume, and 1 mL is equivalent to 1 cubic centimeter ($1\ \text{cm}^3$) because the cubic centimeter is a unit of volume for solids (and is equivalent to the milliliter for liquids). 1 L is 1000 mL, so 1 mL is not 1 L. 1 cm is a unit of length, not volume, so it can't be equal to 1 mL. $1\ \text{m}^3$ is a much larger volume (1 m³ = 1,000,000 mL), so it's not equal to 1 mL.

Answer:

A. $1\ \text{cm}^3$
