How tall is Goliath at six cubits?

Goliath, the Philistine champion from Gath from 1 Samuel chapter 17, stood 6 cubits and 1 span in height which totals about 9.75 feet or 3 meters.

Note the Greek version and Dead Sea Scroll read this as 4 cubits and 1 span which is 6.75 feet (2 meters). In any case Goliath was a giant of a man and some bible translations indicate his height as almost twice as tall as most men.
