🔍 Key Concepts

• Archimedes’ Principle – the weight of the floating jack‑up equals the weight of the water it displaces • How to compute weight from volume × density (cubic feet × pounds per cubic foot) • Unit conversion from pounds to kips (1 kip = 1,000 pounds)

💭 Think About

• If the jack-up displaces 350,000 cubic feet of sea water, how many pounds of water is that, using 64 lb/ft³? • Once you have the weight in pounds, how do you convert that number into kips? • After converting to kips, which of the answer choices is closest to your calculated value?

✅ Before You Answer

• Multiply volume (ft³) by density (lb/ft³) to get total weight in pounds • Use 1 kip = 1,000 lb to convert your answer into kips • Double-check your powers of ten and zeros so your kips value makes physical sense for a large jack-up unit
