Which statement about gauge is true?

• A. It measures the color of metal.
• B. It is a measurement of thickness of metals; the number of sheets of metal necessary to equal approximately one inch of thickness.
• C. It refers to the decorative trim around the lid.
• D. It is a type of lighting.

Answer: (B)

Gauge is a measurement system that expresses how thick a piece of metal is. In sheet-metal and casket construction, the number you see indicates thickness: the lower the gauge, the thicker the metal; higher gauge means thinner metal. The idea that you can think of gauge as the number of sheets needed to reach about one inch captures this relationship in a practical way—more sheets to reach an inch means thinner material, fewer sheets means thicker material. Keep in mind the exact thickness for a given gauge can vary by material (steel, aluminum, copper) because different metals use different gauge standards, but the overall principle remains the same. The other options describe color, decorative trim, or lighting, which aren’t related to gauge.
