Either of the two numbers (see long and short scales for more detail):
1,000,000,000,000 (one million million; 1012; SI prefix: tera-) for all short scale countries (12 zeros)
1,000,000,000,000,000,000 (one million million million; 1018; SI prefix: exa-) for all long scale countries (18 zeros)
12 zeros in a trillion.
There are 15 zeros in the number 6,000,000,000,000,000 (6 trillion). ---- Actually, this is six trillion -> 6,000,000,000,000 so there are actually 12 zeros in 6 trillion.
12.
As a number there are 12
If you mean a number followed by 12 zeros then it is a trillion: e.g. 1,000,000,000,000
The number 35 trillion is written 35,000,000,000,000 - with twelve zeroes.
A trillion.
There are 12 zeros in 3 trillion.
There are 18 zeros in a quin trillion
There are 13 zeros in 80 trillion.
1 Trillion = 100,000,000,000 eleven zeros
there are 12 zeros. 1.000.000.000.000 is one trillion
