I have to make a checker board 40cm by 40cm and it has to have 8 even squares in each row. Is the 40 cm 15 3/4 inches? and how do you measure each square to be equal?

You'll need a ruler with centimeters. Then divide 40 by 8 to find the size (in centimeters) of each square.

To start, let's confirm the conversion from centimeters to inches. One centimeter is equal to 0.3937 inches. Therefore, to convert 40 centimeters to inches, you can multiply 40 by 0.3937. The result is approximately 15.748 inches. So, yes, 40 centimeters is roughly equivalent to 15 3/4 inches.

Next, you need to ensure that the checkerboard has 8 even squares in each row. To do this, you will divide the length of the checkerboard by the number of squares in each row. In this case, you have a 40 centimeter by 40 centimeter checkerboard, and you want 8 squares in each row.

To measure each square to be equal, you will calculate the length of each square. Divide the total length of the checkerboard (in this case, 40 centimeters) by the number of squares in each row (in this case, 8).

By performing the division, 40 cm ÷ 8, you will find that each square should measure 5 cm.
