Cultural Tip
In most Spanish‑speaking countries, box sizes are usually expressed in centimeters (cm) or meters (m) for dimensions, and in liters for volume. When speaking with a supplier, it’s polite to specify the measurement system you prefer. Also, remember that in formal written requests (e.g., emails to a shipping company) you might replace 'necesito' with the more formal 'requiero'.
