suppose a board is 9 meters long how many centimeters long is it
1 meter = 100 centimeters
How many centimeters equals 9 meters?
To convert meters to centimeters, you need to know that 1 meter is equal to 100 centimeters. So, to find out how many centimeters long a 9-meter board is, you can multiply the length in meters by 100.
In this case, you would multiply 9 meters by 100 to get the length in centimeters.
9 meters * 100 centimeters/meter = 900 centimeters
So, a 9-meter board is 900 centimeters long.
