a one meter square sheet of cardboard is cut into the maximum number of squares of side one millimeter. If these squares would be laid side by side, how far would they stretch?

1,000 * 1,000 = 1,000,000 sq. mm. = 1,000 m = 1 kilometer

To determine the maximum number of squares of side one millimeter that can be cut from a one-meter square sheet of cardboard, we need to measure the length of one side in millimeters.

Since there are 1000 millimeters in a meter, the length of one side of the square sheet in millimeters would be 1000 mm. To find the number of squares, we divide the length of the side of the sheet (1000 mm) by the length of one side of the square (1 mm):

Number of squares = Length of sheet side in millimeters / Length of square side in millimeters
= 1000 mm / 1 mm
= 1000 squares

Therefore, a one-meter square sheet of cardboard can be cut into 1000 squares of side one millimeter.

To find out how far the squares would stretch if laid side by side, we need to calculate the total length of the squares.

The total length of the squares can be found by multiplying the number of squares by the length of one side of the square:

Total length of squares = Number of squares x Length of square side
= 1000 squares x 1 mm
= 1000 mm

Therefore, if the squares were laid side by side, they would stretch for a total distance of 1000 millimeters (or 1 meter).
