a skyscraper has a mass of 2.2 x 10^5 tons another skyscraper int he same town has a mass of 3.7 x 10^5 tons what is the combines mass in tons of the two sky scrappers

To find the combined mass of the two skyscrapers, you simply need to add their masses together.

So, 2.2 x 10^5 tons + 3.7 x 10^5 tons = (2.2 + 3.7) x 10^5 tons

This simplifies to: 5.9 x 10^5 tons

Therefore, the combined mass of the two skyscrapers is 5.9 x 10^5 tons.
