2,855,601,061,277,669,291,338,582,677.165 feet.
OR
$2.855 \text{ x " 10^27" feet}$

#### Explanation:

I don't think you understand the scale of the Universe, but:

The observable universe has a diameter of 92 Billion light years, that's 92,000,000,000. 1 Light Year is the distance traveled by light in 1 year and light travels at approximately 186 thousand miles per second, or 983,781,341.35 feet per second. That's almost 984 Million feet in just 1 second. Once we start multiplying by 60 seconds, then 60 minutes, then 24 hours, then 365 days to get to a year, the number becomes 31,039,141,970,409,448.819 or 31 quadrillion feet. That is 1 light year. Now we multiply that by the diameter of the Universe and get:

2,855,601,061,277,669,291,338,582,677.165 feet.
OR if you prefer scientific notation:
$2.855 \text{ x " 10^27" feet}$
