Understanding Volume in the Metric System
Volume is a measure of the amount of space an object occupies. In the metric system, volume is typically measured in liters (L) and milliliters (mL). Understanding how to convert between these units is fundamental in solving problems related to volume.
Common Metric Volume Units
Here are the commonly used metric volume units:
- Milliliter (mL) - One-thousandth of a liter.
- Liter (L) - The primary unit of volume in the metric system.
- Cubic centimeter (cm³) - Equivalent to 1 mL; often used in chemistry and biology.
- Cubic meter (m³) - The standard unit for larger volumes.
Metric Mania Lesson 3: Overview

Answer Key for Metric Mania Lesson 3 Volume
The answer key for Metric Mania Lesson 3 provides solutions to the exercises included in the lesson. Below is a sample answer key that corresponds to common volume problems:
Sample Problems and Answers
1. Convert 250 mL to Liters
Answer: 0.25 L (Since 1 L = 1000 mL, divide 250 by 1000.)
2. Calculate the volume of a cube with side lengths of 5 cm.
Answer: 125 cm³ (Volume of a cube = side³ = 5 cm × 5 cm × 5 cm)
3. If a tank holds 2.5 L of water, how many milliliters is that?
Answer: 2500 mL (Since 1 L = 1000 mL, multiply 2.5 by 1000.)
4. Find the volume of a cylinder with a radius of 3 cm and a height of 10 cm.
Answer: 282.74 cm³ (Volume of a cylinder = πr²h ≈ 3.14 × 3² × 10)
5. How many liters are in 7500 mL?
Answer: 7.5 L (Again, divide 7500 by 1000.)
Using the Answer Key Effectively
To maximize the benefits of the answer key, students should:
- Attempt Problems First: Try to solve the problems independently before referring to the answer key.
- Review Mistakes: Analyze incorrect answers to understand where mistakes occurred.
- Discuss with Peers: Engaging in discussions with classmates can provide different perspectives on solving volume problems.
