Since 12" by 12" is one foot by one foot or one square foot, 1237 of these tiles will feet in 1237 square feet.
The first contour line below the spot elevation of 1237 feet would be at 1220 feet (1237 feet - 20 feet = 1217 feet).
Five, and you still have two inches extra.
66 inches is five feet but 5 and a half is 66.5
