225 meters = 738 feet approximately
Reason:
To convert from meters to feet, we multiply by 3.28
This is because 1 meter is roughly 3.28 feet. It's fairly close to 3 feet which is exactly one yard. A good rule of thumb could be: "1 meter stick is about the same length as a yard stick".
So 225 meters is equivalent to approximately 3.28*225 = 738 feet
For visual comparison, 738 feet is about the height of a 74 story building where every floor is 10 feet tall. Note that 738/10 = 73.8 which rounds to 74.
