Step-by-step explanation: To convert 30 inches into centimeters, we start with our conversion factor for inches and centimeters which is shown below.
1 inch = 2.54 centimeters
Next, notice that we're going from a larger
unit, inches, to a smaller unit, centimeters.
When we go from a larger unit to a smaller unit we multiply by the conversion factor. So here, we multiply 30 times the conversion factor, 2.54 and we get 76.2. This means that 30 inches = 76.2 centimeters.
