[Robert DeLong]

A U.S. ton is 2,000 pounds. But he said they were 20 tons and that was 20,000 pounds 2,000 * 20 - 40,000 pounds. 22 tons would be 44,000 pounds.

But then he clarified that they were metric tons.

A metric ton 2,204.623 pounds. 2,204.623 * 20 = 44,092.46 pounds.

I listened to it to make sure I got exactly what he had said. He said they were 20 ton columns he than clarified that they were metric tons, that means they weighed 20,000 pounds.
