Hey! I'm also new to this forum.

LC this week:
Old Cap'n Bloodhook, the captain of The Black Pawkeet, needed to pack away some of his hoarded dubloons. "I'll tell you what," he said, "if ye can help me figure out how many dubloons can fit into this tray, I'll be givin' ye a reward!"
So the tray is perfectly square, and just big enough to fit 10 dubloons along one side.
So, without overlapping any dubloons, what is the maximum number of dubloons that can fit in the tray?
