CONCRETE
The men used a concrete saw to cut out the broken patch of floor.

I asked Tom how much that pile of concrete weighed. “Just about half a ton,” he said.
“Half a ton?” I said. “That little pile of concrete weighs a thousand pounds?”
"Probably close to it,” said Tom. “Concrete is heavy stuff.”
Incredulous, I did the math:
To refill the hole they would use thirteen sixty-pound bags of concrete, plus twenty-six gallons of water with which to mix it. One gallon of water weighs 8.34 pounds. Altogether that’s 996.84 pounds. Just about half a ton.
