Which of these is the best estimate for the length of a soccer field? Is it 100 centimeters, 10 centimeters, 10 meters, or 100 meters?

If we wanted to measure the length of a soccer field, would we measure using centimeters or meters? The width of an index finger is about one centimeter. Does a soccer field measure 100 index fingers? No, it doesn’t. And the length of a soccer field is not 10 centimeters either. Soccer field measures much more than 10 index fingers.

Would we use meters to measure a soccer field? We know a baseball bat is about a meter in length. If we were to lay out 10 baseball bats in a row, that would be about 10 meters. A soccer field would measure more than 10 meters in length. How about 100 meters? This is the largest unit of measurement we have in our possible answers. So the best estimate for the length of a soccer field is 100 meters. In actual fact, most soccer fields do measure 100 meters in length. The best estimate is 100 meters.
