Squares In Chessboard

Puzzle Details: 

How many squares can you form on a chess board ?

 Solution Explained :

To find the total squares in a square grid or rectangular grid is a common question asked in aptitude tests and many times asked in job interviews also. There are many ways we can solve these kinds of questions, but the most important thing is the approach and the time you are consuming to solve the problem.

many prefer to count the squares logically and come to the conclusion about the number of squares, but with this approach, there are high chances of missing some squares and this is time-consuming. Also, I consider this category of questions as easy ones because if you solve this question logically, it can be done in less than 10 seconds. 

Although the investigation seems quite simple, it requires a methodical approach if the correct answer is to be attained. As the title suggests, the investigation involves candidates finding out how many squares there are on a chessboard. You might think that there are only 64, but you would be wrong...

Answer : There are actually 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 = 204 , squares on a chessboard! (in total 204).
