To convert 75cm to inches, we first need to understand the conversion rate between centimeters and inches. One inch is equal to 2.54 centimeters. This means that to convert from centimeters to inches, we need to multiply the number of centimeters by 2.54.

Step 1: Write down the Given Value

The given value is 75cm.

Step 2: Set up the Conversion Equation

Using a calculator, we can divide 75 by 2.54 to get the final value in inches.

75/2.54 = 29.527559 inches

Step 5: Round off the Result

We should round off the result to the appropriate number of significant figures. Since we are converting from centimeters, which is a smaller unit to inches, which is a larger unit, we should give the final result in two decimal places. Therefore, the final answer is:
