For Exercises 40 and 41, refer to the following. An ancient measure of length, the cubit, was the distance from the elbow to the tip of the middle finger of a person’s outstretched arm. So the length of a cubit depended on the person, though there was some attempt at standardization. Most estimates place the cubit between 17 and 22 in.
41. Goliath [of David and Goliath, as related in the Bible (I Samuel 17:4)] was “six cubits and a span.” A “span” was originally the distance from the tip of the thumb to the tip of the little finger when the hand is fully extended, about 9 in. What range of heights would this indicate for Goliath in feet and inches? In centimeters?
