Square kilometers is a measure of area, not volume or distance.
Your question can not be answered.

I didn't know that the universe was flat. Didn't someone challange that concept a long time ago? I think they were talking about the earth. But, we are part of the universe, aren't we?
Of course if we change to cubic km, then we have a different question. This is a pretty straightforward units conversion if you can get the distance to the edge of the universe.
Assume that the universe is spherical and calculate the volume of the sphere. V=4/3*pi*r^3
r = radius of universe sphere in km
ok?

The present distance (comoving distance) to the edge of the observable universe is larger, due to the ever increasing rate at which the universe has been expanding; it is estimated to be about 78 billion light years[5] (7.8 Ã 1010 light years, or 7.4 Ã 1026 m). This would make the volume, of the known universe, equal to 1.9 Ã 1033 cubic light years (assuming this region is perfectly spherical).

The universe is all around us. It's 3 dimensional. You're question of "square kilometers" can never be answered. Maybe you should try to reword your question like "cube meters, cube kilometers, or cube miles and maybe, someone may calculate. But still, I doubt one can even come close for an estimate. My guees however is, finite.

Since the universe is constantly expanding, and is infinite, there is no way to determine the amount of kilometers.
Our galaxy, however, is around 80,00 to 100,000 light years across, and there are 9.461Ã10 to the 12 km in a light year,
so the answer would take up more space than I can type.
HUGE.

Since the universe is ever expanding, it would be impossible to set a definite number as it would change before you could record it.

Its always expanding. And by the way, you cant measure it in square kilometers. square kilometers is for 2d objects

the ever expanding universe is so large that it is immposible to determine.
also sq kms is a area measurment and not volume

It is impossible to say when the Universe began, past the big bang.
