To find the square root of you have to find out the square root of 108, you will have to find out two numbers that are close to it. so 10 x 10= 100 and 11 x 11 = 111. So the number will be in between 10 and 11. I tried 10.4, which ended up to be 108.16. Since that was over 108 I tried 10.3 x 10.3, and that equals 106.09. That was the closest to 108 without going over. The square root of 108 is  10.3.
