At over 1500m, the average thickness is greater than 1m.

The scientists found in a new study that from 1958 through 1976, the average thickness of the Arctic sea ice was about 10 feet.

Well under 0.4%, based upon an average thickness of 1500 meters.

He said, "What's the average thickness of that stuff above?"

There is snow on the ground 80-100 days per year, with an average thickness of 250 cm in the higher mountain altitudes.

This would explain the coral, which covered the craft to an average thickness of thirty feet.

It was made of a single piece; its average thickness is 0.6 mm.

Estimates of average thickness fall in the range from about 50 to 60 km.

This is smaller than one fifth of the average thickness of a human hair.
