Question

how many cells are there in a human body​

Answer 1

Explanation:

15 trillion cells

Based on an adult man's typical volume, you might conclude that the human body contains 15 trillion cells. So if you pick volume or weight, you get drastically different numbers

Answer 2

Answer:

37.2 trillion cells

37.2 trillion cells. This is not a final number, but it's a very good start. While it's true that people may vary in size–and thus vary in their number of cells–adult humans don't vary by orders of magnitude except in the movies.
