Final answer:
To convert the length of the box from centimeters to feet, divide the length in centimeters by 2.54 to get it in inches, and then divide the length in inches by 12 to get it in feet. The closest length of the box in feet is approximately 2.95 feet.
Step-by-step explanation:
To convert the length of the box from centimeters to feet, we need to use the conversion factor: 1 inch = 2.54 cm. So, to find the length in feet, we first need to find the length in inches by dividing the length in centimeters by 2.54, and then divide the length in inches by 12 to get it in feet. Let's calculate:
Length in inches = 90 cm ÷ 2.54 = 35.43 inches
Length in feet = 35.43 inches ÷ 12 = 2.95 feet
Therefore, the closest length of the box in feet is approximately 2.95 feet.
