What is the square root of one thousand eight hundred fifty nine?
43.11612...
How many square centimeters in a square metre?
ten thousand square centimeters
How many square meters are there in one square kilometre?
The prefix "kilo" means thousand, so a kilometer has 1000 meters. Therefore, the SQUARE kilometer has a million (a thousand squared) square meters.
How many perfect squares exist between one hundred thousand and one million?
I make it 684. Would you like a list? The first time I wrote a program to compare the square root of each number from one hundred thousand to one million, and counted only those that were whole. It was late at night, and by compiling my code this brute force approach cranked out an answer in under 30 seconds. Maybe less, I don't remember. I started to rewrite the same program just now, as I see there has been more activity on this question, but then I realized what a mental midget I had been. In thinking about code optimization it occurred to me that the square root of one million is one thousand, and so to count the perfect squares all I need to do was subtract the integral value of the square root of one hundred thousand (316) from 1000. Each of those numbers has a perfect square in the given range. 1000-316 = 684. Had I bothered to produce a list of numbers from the original program I would have immediately realized my foolishness.
How may square decimeters make 1 square meter?
you need one hundred square decimeters for one square meter because one meter is 10 decimeters, and since 10x10=100 it's a hundred decimeter
