Answer:

#6^20# > 3656158.44 billion.

Explanation:

Any of the six digits could appear on the exposed face of a dice, Showing of a face by a dice is arbitrary. So is the appearance of a face in everyone of 20 dices. Hence, the number of 20-digit numbers that could be displayed is 6 X 6 X 6 X .... 20 times. = #6^20#.
