Which capacity unit is used for dry bulk cargo tanks?

• A. Cubic feet
• B. Gallons
• C. Liters
• D. Barrels

Answer: (A)

The capacity of a dry bulk cargo tank is a measure of its space, i.e., its volume. For solids carried in bulk, that volume is typically expressed in cubic feet in many contexts, especially in US customary practice, because it directly describes how much physical space the cargo can occupy inside the tank. The other options—gallons, liters, and barrels—are units commonly used for liquids (volume of fluid in a container or vessel) and aren’t the standard way to express the capacity of a dry bulk tank. If metric were being used, you’d often see cubic meters, but among the given choices, cubic feet best fits the way dry bulk tank capacity is stated.
