Sum of the first 1108 square numbers

We define square numbers as numbers that when squared will equal a whole number. Thus, the list of the first square numbers starts with 1, 4, 9, 16, and so on.

What is the sum of the first 1108 square numbers, you ask? Here we will give you the formula to calculate the first 1108 square numbers and then we will show you how to calculate the first 1108 square numbers using the formula.

The formula to calculate the first n square numbers is displayed below:

		n(n + 1) × (2(n) + 1)
		6

To calculate the sum of the first 1108 square numbers, we enter n = 1108 into our formula to get this:

		1108(1108 + 1) × (2(1108) + 1)
		6

First, calculate each section of the numerator: 1108(1108 + 1) equals 1228772 and (2(1108) + 1) equals 2217. Therefore, the problem above becomes this:

		1228772 × 2217
		6

Next, we calculate 1228772 times 2217 which equals 2724187524. Now our problem looks like this:

		2724187524
		6

Finally, divide the numerator by the denominator to get our answer:

2724187524 ÷ 6 = 454031254

There you go. The sum of the first 1108 square numbers is 454031254.
