1 litre = 10,00,000 mm^3
5 litres = 5×10,000,000mm^3 = 50,00,000 mm^3
RBC in 1 mm^3 of blood = 5.5 million
So, RBC in 5 litres of blood = RBC in 50,00,000 mm^3 of blood
= 5.5 million × 50,00,000
= 5,500,000 × 50,00,000
= 2,75,00,00,00,00,000
= 275 trillion = 2.75 × 10^13
Answer- The no. of RBC in 5 litres of blood is 2.75×10^13.
