How long in centimetres would a line of 1000 base 10 rods be and why?

Oh, what a lovely question! If we have 1000 base 10 rods, each measuring 1 meter long, that would be 1000 meters in total. Since 1 meter is equal to 100 centimeters, the line of 1000 rods would be 100,000 centimeters long. Just imagine all the beautiful landscapes and happy little trees you could paint along that long, long line!

How did we measure a building when there was no rulers?

The earliest known length measurement unit is the cubit: the length from the point of a bent elbow to the tip of the longest finger. Because this length varies from person to person the King's arm was used as the standard cubit and "cubit rods" were cut to that length and used by everyone else to measure lengths and distances. Other units were determined similarly: the standard foot being the length of the king's foot, the inch is the length of 3 barley corns placed end to end, etc.
