The surface area of the earth is about 510 million square kilometers, which is equivalent to the total area of football fields? (football field area is about 7000 square meters) This number is quite large. How can we explain it to the students of grade one?

The surface area of the earth is about 510 million square kilometers, which is equivalent to the total area of football fields? (football field area is about 7000 square meters) This number is quite large. How can we explain it to the students of grade one?

7000 square meters = 0.007 square kilometers
Distance = 5.1 △ 0.007 ≈ 72.9 billion

Hectare and mu, square meter how conversion? 400 meters track football field about how many mu?

1 mu = 666.667 square meters
1 ha = 10000 M2
The football field is 10.9 mu

How many football fields is 60000 square meters?

The football field is rectangular. Its length shall not be more than 120 meters or less than 90 meters, and its width shall not be more than 90 meters or less than 45 meters. In any case, the length must exceed the width. FIFA's standard football field is 105 meters long and 68 meters wide
Therefore, the area of football field should be from 45 × 90 = 4050 square meters to 90 × 120 = 10800 square meters, and the area of standard match field is 105 × 68 = 7140 square meters
So 60000 square meters--
Up to 14 pitches,
The smallest is the area of five football fields,
According to the standard stadium, it should be as big as eight football fields
