Put the 7cm and 5 cm rods together = 12 cm
Put the 9cm and 2cm rods together = 11 cm
Difference between is 1cm thus, you can use that difference to measure 1 cm.
40 square rods = 1/4 acre.
The metric system is far superior to the archaic one you are struggling with. Please stop wasting your time; study the metric system.
Different acre equivalents: * 43,560 square feet * 4,840 square yards * 160 square rods * 1/640 square mile (that is, 0.001 562 5 sq. mile) * is about 0.404 687 3 hectare
11cm
You do not need "white rods", you need a tape measure or a ruler to measure the lenght of your thumb.
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!
None. A rod is a measure of length or distance while an acre is a measure of area. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
Need length of rods in question to answer.
66 feet is 2 rods.
Lay the 5cm & 7cm end-to end - which gives you a length of 12cm.Lay the 9cm & 2cm end-to end - which gives you a length of 11cm.Now - lay both pairs next to each other - making sure one end is flush with it's neighbour. The difference is 1cm. Something like this....-----|----------------|--The vertical bar is just for clarity.
There are 4 rods in a chain. Each rod is equal to 1/4 of a chain.
There are generally found to be 45.72 centimeters in a cubit. A cubit is an old-fashioned measure based on the length from middle finger to elbow, so there are going to be some variations with the absolute figure.
YES they should be.
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.
