How to Convert Inches Square to Centimeters Square
Example: How many centimeters square are equivalent to 39.74 inches square?
As;
1 inches square = 6.4516 centimeters square
39.74 inches square = Y centimeters square
Assuming Y is the answer, and by criss-cross principle;
Y equals 39.74 times 6.4516 over 1
(i.e.) Y = 39.74 * 6.4516 / 1 = 256.386584 centimeters square
Answer is: 256.386584 centimeters square are equivalent to 39.74 inches square.
