To calculate the surface area of the earring box, we need to find the area of each face of the box and then add them up.
The dimensions of the box are:
Length = 12 cm
Width = 6 cm
Height = 4 cm
Calculating the area of each face:
1. Front and back faces: 12 cm * 4 cm = 48 cm^2 (2 faces)
2. Top and bottom faces: 12 cm * 6 cm = 72 cm^2 (2 faces)
3. Side faces: 6 cm * 4 cm = 24 cm^2 (2 faces)
Adding up all the areas:
48 cm^2 + 48 cm^2 + 72 cm^2 + 72 cm^2 + 24 cm^2 + 24 cm^2 = 288 cm^2
Therefore, the surface area of the earring box is 288 cm^2. Rounding this to the nearest whole number gives us 288 cm^2.
