🔍 Key Concepts

• Density of seawater (about 64 lb per cubic foot) • Relationship between weight (tons) and volume (cubic feet, gallons, liters) • Conversion between pounds and tons

💭 Think About

• If seawater weighs about 64 lb per cubic foot, how many cubic feet are needed to reach about one ton of weight? • Once you find the approximate cubic feet for one ton, which option (liters, gallons, cubic feet) most closely matches that volume? • How do the approximate equivalents between cubic feet, gallons, and liters help you eliminate clearly wrong answers?

✅ Before You Answer

• Be sure you use long ton ≈ 2,240 lb (as commonly used in seamanship questions), not short ton • Confirm that seawater is heavier than freshwater, so use about 64 lb/ft³, not 62.4 • After you find the volume in cubic feet, check unit conversions before matching it to one of the choices
