Step 1: Set up the conversion.
Since 1 inch = 2.54 centimeters, we can set up a proportion to convert from centimeters to inches.
78.04 cm * 1 inch/2.54 cm = x
Step 2: Multiply and solve the equation.
78.04 cm * 1 inch/2.54 cm = 30.7 inches.
The final answer is 30.7 inches.
Step 3: Compare to known objects.
30.7 inches is approximately the length of a standard ruler (30.48 cm) or the width of a standard door (30 inches). It is also slightly longer than the length of an average laptop computer (29.5 cm).
