How many whole numbers between 39 and 160 are perfect squares

Sure, let's solve this step by step:

1. First, we need to find the square root of the first number, which is 39. The square root of 39 is approximately 6.24. Since we are looking for whole numbers, we need to round this up to the next whole number, which is 7.

2. Next, we find the square root of the second number, which is 160. The square root of 160 is approximately 12.65. Since we are looking for whole numbers, we need to round this down to the nearest whole number, which is 12.

3. Now, we have the range of numbers whose squares fall between 39 and 160. These numbers are 7, 8, 9, 10, 11, and 12.

4. Therefore, there are 6 whole numbers between 39 and 160 that are perfect squares.
