To find the surface area of the box, we need to calculate the area of each of the six sides and then add them together.
1. Top and bottom: 14 cm x 7 cm = 98 cm^2 (x 2 sides)
2. Front and back: 14 cm x 1.66 cm = 23.24 cm^2 (x 2 sides)
3. Sides: 7 cm x 1.66 cm = 11.62 cm^2 (x 2 sides)
Total surface area = (98 x 2) + (23.24 x 2) + (11.62 x 2)
Total surface area = 196 + 46.48 + 23.24
Total surface area = 265.72 cm^2
Therefore, the surface area of the earring box is 266 cm^2 when rounded to the nearest whole number.
