square numbers are the numbers that are... 1x1=1 2x2=4 3x3=9 4x4=16 ..... 1,4,9,16,25,36,49,64,81,100,121,144.........
1x1 = 1 2x2 = 4 3x3 = 9 4x4 = 16 ... Up to 31x31

1x1 = 1 2x2 = 4 3x3 = 9 4x4 = 16 5x5 = 25 6x6 = 36 you get the picture...49, 64, 81, 100, 121, 144, 169, etc.
A perfect square (commonly square number) is an integer that is the square of another integer. That is to say, a perfect square is the product of any whole number multiplied by itself.Commonly remembered perfect squares include, 1 (1x1), 4 (2x2), 9 (3x3), 16 (4x4) and 25 (5x5).

The 1st 3 square numbers are 1 (1x1), 4 (2x2) and 9 (3x3)

1x1=1 2x2=4 3x3=9 4x4=16 5x5=25 These are squared numbers.
Just calculate the square numbers: 1x1, 2x2, 3x3, 4x4, etc., until you get a square that is larger than 130.
They are ............................. 1x1=1 2x2=4 3x3=9 4x4=16 5x5=25 6x6=36 7x7=49 AND ON AND ON AND ON ..........
There 64 1x1 squares on a chessboard. There are also 49 2x2 squares, 36 3x3 squares, 25 4x4, 16 5x5, 9 6x6, 4 7x7 and 1 8x8. Total number of squares on a chessboard is therefore 204.
1, 4, 9, 16, 25, 36, 49, 64, 81, etc work it out as 1x1, 2x2, 3x3, 4x4 etc
16 Answer #2 It is 16 if you just count the 1 x 1 squares but the 16 squares also form a 4x4 square. There are also 2x2 squares and 3x3 squares in the pattern. 16 1x1 squares 9 2x2 squares 4 3x3 squares 1 4x4 square 30 squares (possibly more?)
8x8=64(1x1)7x7=49(2x2)6x6=36(3x3)5x5=25(4x4)4x4=16(5x5)3x3=9 (6x6)2x2=4 (7x7)1x1=1 (8x8)64+49+36+25+16+9+4+1=204Total=204
There are 36 unique quadrilaterals in a 3x3 square grid: 14 squares = 9 (1x1) 4 (2x2) 1 (3x3) 22 rectangles = 6 (1x2) 6 (2x1) 6 (3x3) 2 (2x3) 2 (3x2) (the total number of quadrilaterals formed by 3 x 3 pin sets will be larger, i.e. 78)
