1.	Rad corpuscles of human blood stream are known to be flattened discs. Blood count shows `RBC_s` of sdhte order of `5xx10^6` in each cubic millimeter of blood. If the adult body contains 5 litres of blood, what is the order of total number of red corpuscles it contains?
Answer» Correct Answer - `10^(13)` Number of `RBC_s in 1mm^3 = 5xx10^6` Total volume fo blood = 5 litres `5xx10^3xx10^3 mm^3` Total number of `RBC_s = 5xx10^6xx5xx10^6` `2.5xx10^(13) ~~10^(13)`
