Given :  join all the A4 sheets used by humans in a year and make a huge sheet in the same ratio as A4,  The average consumption of papers per human on an average is 55 Kg. Assume the weight of a bundle of 500 A4 papers is 2 Kg. The current world population is 7.8 billion.​

To find : what will be the appropriate estimation for the sides of this huge sheet?

Solution:

population = 7.8 Billion = 7.8 * 10⁹

The average consumption of papers per human on an average is 55 Kg

Hence total consumption = 7.8 * 10⁹ * 55

= 429 * 10⁹  kg

2 Kg = 500

=> 1 kg = 250

=  429 * 10⁹ * 250

= 1,07,250  * 10⁹

= 107.25 * 10¹²

A4 Sheet size  =  297 mm * 210 mm

Area = 297 * 210  mm²

= 62370  mm²

Total area  = 107.25 * 10¹² * 62370  mm²

= 6.689 * 10¹⁸  mm²  

1 m = 10³ mm

=> 1 m² = 10⁶ mm²

1 km² = 10⁶ m² = 10¹² m²

6.689 * 10⁶  km²  

2.175 x 10³   * 3.076 10³  km²  

= 2175 km x 3076 km

appropriate estimation for the sides of this huge sheet

2175 km  x 3076 km
