The combined mass of the two skyscrapers is 5.9×10^5 tons.
wrong
Apologies for the mistake. Let's calculate the combined mass correctly.

The mass of the first skyscraper is 2.2×10^5 tons, and the mass of the second skyscraper is 3.7×10^5 tons.

To find the combined mass, we add the masses of the two skyscrapers:

Combined mass = 2.2×10^5 + 3.7×10^5
Combined mass = 5.9×10^5 tons

Therefore, the combined mass of the two skyscrapers is 5.9×10^5 tons.
still wrong
Apologies for the mistake once again. Let's calculate the combined mass correctly.

The mass of the first skyscraper is 2.2×10^5 tons, and the mass of the second skyscraper is 3.7×10^5 tons.

To find the combined mass, we simply add the masses of the two skyscrapers:

2.2×10^5 + 3.7×10^5 = 5.9×10^5

Therefore, the combined mass of the two skyscrapers is 5.9×10^5 tons.
wrong again
I apologize for the incorrect responses earlier. Let's calculate the combined mass correctly.

The mass of the first skyscraper is 2.2×10^5 tons, and the mass of the second skyscraper is 3.7×10^5 tons.

To find the combined mass, we need to add the masses of the two skyscrapers:

2.2×10^5 + 3.7×10^5 = 5.9×10^5 tons

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