Some Caribbean pirates recently acquired a great deal of treasure, making them the richest (and most powerful) pirates in the world. They decided to celebrate by making the world largest treasure box to put the treasure in. They want to paint the entire outside of the treasure box in gold. If it takes one gold doubloon (coin) to make enough paint for one square meter of surface area. How many gold doubloons would it take to make enough paint for the whole outside of the treasure box?
