The no. Of red blood cells per cubic millimeter of blood is approximately 5.5 million . if the average body contains 5 litres of blood what is the total no. Of blood red cells in the body ( 1 litre = 1,00,000 mm³)
Answers
Answer:
2750000 million RBC
Step-by-step explanation:
∵1 litre = 100,000 mm³
∴5 litre = 5×100,000 mm³
=500,000 mm³
∵1 mm³= 5.5 million
∴500,000 mm³= 500,000×5.0
=2750000 million answer

Answer:
Ans:- Total number of red cells in the body = 2.75 × 10^12
Step-by-step explanation:
Given :-
No. of red blood cells per cubic mm of blood is approx. 5.5 million.
The average body contains 5L blood.
To Find :-
Total number of red blood cells in body
Red blood cells in body = 5.5 million = 5.5 × 1000000mm^3
Blood in body = 5L = 5 × 100000 mm^3
Hence total blood = 5 × 100000 × 5.5 × 1000000
Hence total blood = 5 × 100000 × 5.5 × 1000000
= 5 × 100000 × 55 × 100000
= 5 × 55 × 10^10
= 275 × 10^10
Hence in standard form it can be written as,
Total number of red cells in the body = 2.75 × 10^12
Ans:- Total number of red cells in the body = 2.75 × 10^12
