The surface area of the box that needs to be decorated is:
- Front: 27 cm x 20 cm = 540 square centimeters
- Top: 27 cm x 20 cm = 540 square centimeters
- Left side: 20 cm x 20 cm = 400 square centimeters
- Right side: 20 cm x 20 cm = 400 square centimeters
Total surface area of the box that needs to be decorated = 540 + 540 + 400 + 400 = 1880 square centimeters.
