Why cant you find a square number which is double another?

Because you are squaring numbers, the only way to get double is by using the square root of 2 which is 1.414. A good example of this is paper sizes. A4 is 210x297 A3 is double the size of A4 but to get that you need to multiply the sides by 1.414. That gives 297x420 But if you double each side of A4 you get 420x594 which is A2 and that is 4 times as big as A4 not 2 times as big.

First of all the square root of something isn't the number you get when you multiply it by itself, the square root of something is the number that multiplys by itself to get that number so the square root of 36 is 6 but I don't know how to get the square root of a really big number. My answer isUSE A CALCULATOR!!!
