3·109 x 0,34·10-9 = 1 m
1 m x 75·1012 = 75·1012 m
= ten thousand times to the Moon and back again = 500 return trips to the Sun
You can calculate this in two ways, considering that there are 3 billion
base PAIRS present in a cell. Strictly taken, you should write down 6
billion bases in the books. Nevertheless, calculating with only 3
billion bases is also correct since they are complementary to the other
3 billion. This calculation takes 6 billion bases into account:
For each book: 107 bases (1000 x 10000). So we need 600 books with a total height of 600 x 5 cm = 3000 cm = 30 m
You only need 2 DVDs and even less if you use some kind of data compression.
