If its 98 degrees outside, whats the temp inside?

Question

Its a school with no AC and 25 kids.

Answer 1

Depends on whether the AC is on or not, what the AC is set on, how much shade is over the house, etc

Answer 2

Not enough information to calculate anything.  I would need to know what kind of material the walls were made from... if they have insulation... so as to know the specific heat of the walls.  And then I would need to know the amount of window space,  whether the windows are up or down among other things.  

Either way, it's likely warmer inside with no A/C as the radiation comes in and bounces around the room increasing the temperature.  Probably 105-110F.
