I would like to mention that some ants around the world could not only lift 40 times their weight, but some can lift over 100 times their own body weight while upside down on glass. 

I'm not a math expert, but I will say that Ash is strong, but she isn't powerful enough to pick up a building, she could pick up a car and a large boulder, but something of a house, building, or the school would be far beyond her strength.
