Two of them.
8
Make a grid of 8 squares by 8 squares, with alternate squares coloured, normally black and white.
Squares are actually also rectangles so you could make 8 rectangles without touching any of the squares. However, if you could cut the squares, that would be a different problem....
There are: 8*8 = 64 squares
8 x 8 = 64 squares
There are 64 squares on a chess board and you get this from the 8 times 8= 64
An 8 by 8 grid would have 64 squares(multiply 8 times 8 to get the square).
Eight (8) squares make up one side of a checker board. There is a total of 64 squares. The squares are arranged in eight rows of eight squares each.
There are 64 squares as on a chess board. This is assuming that 8 by 8 in the question means 8 rows and 8 columns.
8 squares per row. A chess board is made up by 8 x 8 squares.
There are 64, it is an 8 by 8 grid.
8X8=64
