Final answer:
To convert the length of the box from centimeters to feet, divide by 2.54 and then divide by 12.
Step-by-step explanation:
To convert centimeters to feet, we need to use the conversion factor 1 inch = 2.54 cm. Since there are 12 inches in a foot, we can divide the length of the box by 2.54 and then divide the result by 12 to get the length in feet. Let's calculate:
Length in feet = (20 cm / 2.54 cm/in) / 12 in/ft
Length in feet = 0.66 feet (approximately)
