🔍 Key Concepts

• Twenty-foot Equivalent Unit (TEU) as a standard shipping measure • How container ship capacity is usually expressed (e.g., 5,000 TEU, 10,000 TEU) • Typical ISO standard container lengths used in ocean shipping

💭 Think About

• When you see the term "equivalent unit" in container shipping, what common abbreviation is usually used with it? • Think about the most common container size historically used to define ship capacity—what length is that based on? • Of the options given, which length is traditionally associated with the word used in the phrase "___-foot equivalent unit"?

✅ Before You Answer

• Identify what TEU stands for and which number goes in front of "foot" • Confirm which of the answer choices matches that specific foot-length • Make sure you’re not confusing the base unit with the larger containers often used today (like the one that is exactly double the base length).
