Are all her squares the same size? (I have the right to see part that space bigger 보다 others...)How plenty of different size of square are there?How plenty of squares space there of every size?Would it help to begin by counting the squares on a smaller board first?Is over there a quick method to work out how countless squares there would certainly be top top a 10x10 board? Or 100x100? Or...?What about a rectangular chessboard?



There space 64 block which room all the very same size. All you had to perform was 8 time 8 which equals 64 since it is aboard that is 8 by 8.

You are watching: How many squares does a checker board have


I can see what you mean, but...

I check out the 64 squares you mean. I can see some other squares too, of various sizes. Deserve to you discover them? / Chessboard squares

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

Mathematics / Chessboard

Luisa experienced that there were bigger squares because the inquiry is "How plenty of squares room there?" yet it doesn't clarification what form of squares, so there space bigger and also smaller squares, meaning, there are an ext than 64 squares. The bigger squares space composed by smaller squares. Therefore a large square would have 4 mini little squares. (Bigger ones could have an ext :) )

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

Chessboard Challenge

The answer is 204 squares, because you have to include all the square numbers from 64 down.


That's an amazing answer

That"s an exciting answer - have the right to you explain why you have to include square numbers?What around for different sized chessboards?

represent each type of square

represent each type of square together a letter or symbol ,and use that together a quick means to occupational out how many of each kind of square.


Interesting strategy - could

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


you deserve to work this the end by drawing 8 separate squares, and on each discover how many squares the a details size room there. For 1 by 1 squares there are 8 horizontally and also 8 vertically so 64.For 2 by 2 there room 7 horizontally and 7 vertically for this reason 49 . For 3 by 3 there room 6 and also 6, and also so on and you discover that ~ you have actually done that for 8 by 8 you can go no much more so add them up and also find there are 204.


There are actually 64 little squares, but you can make larger squares, such as 2 time 2 squares

chessboard challenge

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


Have friend missed some?

Some world have said there are much more than 101 squares. Perhaps you have missed part - I deserve to spot some 3 by 3 squares for example.

answer strategy

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

Chess plank challenge

There space 165 squares since there room 64 that the tiniest squares and also 101 squares of a different bigger size, combine the tiniest squares right into the enlarge ones.


How go you job-related it out?

I found much more than 101 bigger squares. Exactly how did you work-related them out? maybe you to let go a few.

Total 204 squares

My solution

I pertained to the conclusion the the prize is 204.

Firstly, I resolved that there were 64 'small squares' on the chess board.

The following size increase from the 1x1 would certainly be 2x2 squares.Since there space 8 rows and columns, and there is an 'overlap' of one square for each of these, there are 7 2x2 squares on each row and each column, so there room 49. What I median by overlap is how many squares much longer by length each square is than 1.

For 3x3 squares, there is an overlap that 2, and also so there space 8 - 2 squares every row and also column, and also therefore 6x6 that these, i m sorry is 36.

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

This is repeated for all other possible sizes of square up to 8x8 (the whole board)

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

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

Interestingly, the quantities of the squares are square number which decrease as the size of the square boosts - this renders sense as the larger the square, the less likely there is going to be sufficient space in a given area because that it to fit. It also makes sense that the quantities are square numbers as the shapes we room finding space squares - therefore, the is logical the their quantities vary in squares.
