In the cylinder volume problem, which unit is used for the volume?

• A. Cubic Inches
• B. Cubic Feet
• C. Gallons
• D. Liters

Answer: (B)

Volume is a three-dimensional measurement, so its unit is a cube of the length unit used. In a cylinder volume problem, you use V = π r^2 h. If the given dimensions are in feet, then r and h are in feet, and the resulting volume is in cubic feet. This keeps the units consistent with the measurements. Gallons and liters are also volume units, but they wouldn’t come out directly from feet without a conversion. If the problem had used inches instead of feet, the volume would be in cubic inches. So, with dimensions in feet, the volume is expressed in cubic feet.
