How Many Rhode Islands Fit in Maine? It's a Category Error

Rhode Island is a state, not a unit of area. You can't "fit" one state into another like tiles.

For area comparison:

• Rhode Island: 4,001 km² (1,545 mi²) – land + water.
• Maine: 91,646 km² (35,385 mi²).
• Ratio: Maine ≈ 23× Rhode Island by total area.

So you could fit about 23 Rhode Islands' worth of area inside Maine—but not the state itself.
