🔍 Key Concepts

• Archimedes' principle – a floating body displaces its own weight of water • How to convert cubic feet of seawater to pounds, then pounds to long tons • The density of seawater is given as 64 lb/ft³

💭 Think About

• First, how do you find the weight (in pounds) of the water displaced by 700,000 cubic feet of seawater? Write that as a simple multiplication. • Once you have total pounds, what exact number of pounds is in one long ton (not a short ton or metric ton)? • After converting pounds to long tons, which answer choice is closest to your computed value?

✅ Before You Answer

• Be sure you multiply volume × 64 lb/ft³ to get total weight in pounds. • Confirm that you are using 2,240 pounds per long ton for the conversion. • Double-check your division and compare your result carefully with each option before choosing.
