What principle is applied when calculating the number of shelving units to buy, regarding partial units?

• A. Round up to the nearest whole unit
• B. Always round down to favor cost savings
• C. Ignore expansion needs
• D. Use only current space

Answer: (A)

When planning how many shelving units to buy, you’re turning a required capacity into whole, indivisible items. You can’t purchase a fraction of a shelf, so you round up to the next whole unit. This guarantees the total shelving available meets or exceeds what you need, even when the calculation yields a partial unit. The extra full unit also provides a small buffer for future items or rearrangements. Rounding down would leave you short, and ignoring expansion needs or sticking only to current space would miss the possibility of growth.
