🔍 Key Concepts

• Cubic feet to gallons conversion in U.S. customary units • The exact number of U.S. gallons in one cubic foot • How to use dimensional analysis to convert between volume units

💭 Think About

• First, recall or look up how many cubic inches are in 1 cubic foot, then how many cubic inches are in 1 U.S. gallon. How can you combine those two facts? • If 1 gallon is about 231 cubic inches, how does that help you find how many gallons fit into 1 cubic foot (which is 12 in × 12 in × 12 in)? • Once you get a numerical result, which choice is closest to your calculated value?

✅ Before You Answer

• Verify the exact value of 1 cubic foot in cubic inches before calculating • Verify the standard conversion of 1 U.S. gallon in cubic inches (not Imperial gallons) • After your calculation, check if your answer is reasonable: is it closer to 5, 6, 7, or 8 gallons based on the math, not just guessing?
