Are all your squares the exact same size? (I deserve to see some that are bigger than others...)How countless different sizes of square space there?How plenty of squares are there of each size?Would it aid to start by counting the squares ~ above a smaller board first?Is over there a quick means to occupational out how countless squares there would be top top a 10x10 board? Or 100x100? Or...?What about a rectangle-shaped chessboard?



There are 64 block which room all the exact same size. Every you had to perform was 8 times 8 which amounts to 64 because it is aboard that is 8 through 8.

I can see what girlfriend mean, but...

I check out the 64 squares friend mean. I can see some other squares too, of different sizes. Can you uncover them? / Chessboard squares

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

Mathematics / Chessboard

Luisa saw that there to be bigger squares because the concern is "How numerous squares are there?" but it doesn't clarify what kind of squares, therefore there space bigger and smaller squares, meaning, over there are more than 64 squares. The enlarge squares space composed by smaller sized squares. Therefore a large square would have actually 4 mini small squares. (Bigger ones can have much more :) )

PS: If a concern is posted by Cambridge, well we have the right to guess it won't it is in some an extremely easy questions. :)

Chessboard Challenge

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


That's an interesting answer

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

represent each kind of square

represent each form of square together a letter or prize ,and use that together a quick way to occupational out how numerous of each kind of square.


Interesting strategy - could

Interesting strategy - might you describe a little more about just how you might use it to uncover the solution?


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


There space actually 64 small squares, yet you can make enlarge squares, such together 2 time 2 squares

chessboard challenge

we have predicted the there space 101 squares ~ above the chessboard. There room 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 girlfriend missed some?

Some human being have said there are much more than 101 squares. Maybe you have missed some - I deserve to spot some 3 by 3 squares because that example.

answer strategy

The price is 204.My method: If you take it a 1 by 1 square you have one square in it. If you take a 2 by 2 square you have 4 tiny squares and 12 by 2 square. In a 1 by 1 square the answer is 1 squared, in a 2 by 2 square the answer is 1 squared + 2 squared in a 3 by 3 square the answer is 1 squared + 2 squared + 3 squared, etc. For this reason 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 to 204.

Chess board challenge

There room 165 squares because there space 64 the the tiniest squares and 101 squares that a various bigger size, combining the tiniest squares into the bigger ones.


How walk you work-related it out?

I found more than 101 bigger squares. Just how did you work them out? perhaps you missed a few.

Total 204 squares

Total 204 squares8×8=17×7=46×6=9......1×1=64Total204

My solution

I concerned the conclusion the the price is 204.

Firstly, I cleared up that there to be 64 'small squares' top top the chess board.

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

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

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

This is recurring for all other possible sizes of square approximately 8x8 (the whole board)

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

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

Interestingly, the amounts of the squares are square number which decrease as the size of the square increases - this renders sense as the larger the square, the much less likely over there is walk to be sufficient room in a provided area for it come fit. It additionally makes feeling that the amounts are square numbers together the shapes we room finding room squares - therefore, it is logical that their amounts vary in squares.
