Solution

The relationship between the numbers in the first pair is that the second number is the cube of the first number minus 1.

Step 1: Identify the relationship in the first pair 9 is the square of 3 and 28 is one less than the cube of 3 (27+1).

Step 2: Apply the same relationship to the second pair 65 is the square of 8, so we cube 8 and subtract 1 to find the number that 65 is related to.

Step 3: Calculate The cube of 8 is 512, and 512 minus 1 is 511.

So, 65 is related to 511 in the same way that 9 is related to 28. Therefore, the answer is 511.
