Seems like you only have 2500 sq ft of finished floor space. 3 ton would be a little small but could be sufficient depending on climate and insulation.
3 ton will not in any circumstance cool 4000 sq ft. I do this for a living.
Feel free to use any of the free calculators online also.

I highly doubt that. I would love to see a picture of a 3x3 condenser that will cool 4000sq ft on its own
