Are all your squares the very same size? (I deserve to see some that room bigger 보다 others...)How plenty of different size of square space there?How numerous squares are there of each size?Would it help to start by counting the squares on a smaller sized board first?Is over there a quick way to work-related out how countless squares there would certainly be on a 10x10 board? Or 100x100? Or...?What about a rectangular chessboard?



There room 64 blocks which are all the exact same size. All you had actually to do was 8 times 8 which equals 64 due to the fact that it is aboard the is 8 by 8.

You are watching: How many squares on a checkers board


I can see what you mean, but...

I view the 64 squares friend mean. I can see some other squares too, of various sizes. Can you find them? / Chessboard squares

I likewise see there room 64 squares ("cause 8 x 8 is 64). However, every the squares have actually the same size. Why? Well, i measured it through a ruler and also they all have actually the exact same size. Sometimes, our eyes watch illusions instead of the reality. Examine it.

Mathematics / Chessboard

Luisa experienced that there were bigger squares because the inquiry is "How many squares room there?" yet it doesn't clarify what form of squares, so there are bigger and smaller squares, meaning, there are much more than 64 squares. The larger squares space composed by smaller sized squares. For this reason a large square would have actually 4 mini little squares. (Bigger ones could have more :) )

PS: If a question is posted by Cambridge, fine we have the right to guess the won't be some really easy questions. :)

Chessboard Challenge

The price is 204 squares, due to the fact that you have to include all the square numbers from 64 down.


That's an amazing answer

That"s an interesting answer - have the right to you describe why you have actually to add square numbers?What about for various sized chessboards?

represent each kind of square

represent each form of square together a letter or price ,and usage that together a quick means to work-related out how numerous of each kind of square.


Interesting strategy - could

Interesting strategy - might you explain a little more about exactly how you could use the to find the solution?


you have the right to work this the end by drawing 8 separate squares, and on each discover how plenty of squares of a specific size are there. Because that 1 by 1 squares there room 8 horizontally and 8 vertically so 64.For 2 by 2 there are 7 horizontally and also 7 vertically for this reason 49 . Because that 3 by 3 there room 6 and also 6, and also so on and you find that after you have actually done that for 8 by 8 you can go no much more so include them up and also find there space 204.


There space actually 64 small squares, however you deserve to make larger squares, such together 2 times 2 squares

chessboard challenge

we have actually predicted that there room 101 squares on the chessboard. There are 64 1 by 1 squares,28 2 by 2 squares,4 4 by 4 squares,4 6 by 6 squares,1 8 by 8 square ( the chessboard)


Have friend missed some?

Some human being have claimed there are more than 101 squares. Perhaps you have missed part - I deserve to spot part 3 by 3 squares for example.

answer strategy

The price is 204.My method: If you take a 1 by 1 square you have actually one square in it. If you take it a 2 by 2 square you have actually 4 little squares and 12 by 2 square. In a 1 by 1 square the price is 1 squared, in a 2 by 2 square the prize is 1 squared + 2 squared in a 3 through 3 square the price is 1 squared + 2 squared + 3 squared, etc. So in an 8 by 8 square the answer is 1 squared + 2 squared+ 3 squared + 4 squared + 5 squared + 6 squared + 7 squared + 8 squared i beg your pardon is equalled come 204.

Chess plank challenge

There are 165 squares due to the fact that there are 64 of the tiniest squares and also 101 squares of a different bigger size, combine the tiniest squares right into the enlarge ones.


How did you work-related it out?

I found an ext than 101 bigger squares. Exactly how did you occupational them out? probably you missed a few.

Total 204 squares

My solution

I involved the conclusion that the answer is 204.

Firstly, I settled that there to be 64 'small squares' on the chess board.

The following size up from the 1x1 would be 2x2 squares.Since there space 8 rows and also columns, and also there is one 'overlap' that one square for each that these, there space 7 2x2 squares on each row and also each column, so there space 49. What I typical by overlap is how numerous squares longer by length each square is 보다 1.

For 3x3 squares, over there is an overlap of 2, and so there room 8 - 2 squares per row and also column, and also therefore 6x6 that these, which is 36.

For 4x4 squares, the overlap is 3, for this reason there room 5 every row and also column, leave 25 squares.

This is repetitive for every other feasible sizes of square up to 8x8 (the entirety board)

5x5: 166x6: 97x7: 48x8: 1

64+ 49 + 36 + 25 + 16 + 9 + 4 + 1 = 204.

Interestingly, the quantities of the squares space square numbers which decrease together the dimension of the square boosts - this makes sense as the bigger the square, the less likely over there is walking to be sufficient space in a provided area because that it come fit. It also makes sense that the quantities are square numbers as the forms we are finding space squares - therefore, it is logical the their amounts vary in squares.
