A desk calendar in Figure 1 consists of two congruent white square cardboards on the front and back, and an orange rectangular cardboard as the base. The height of this calendar is 12 cm. When this calendar is folded outward along the dashed line in the middle of the cardboard at its base in the direction shown by the arrow in Figure 2, the appearance in Figure 3 is obtained. In Figure 3, the perimeter of the white cardboard on the front is 12 cm more than the perimeter of the orange-colored cardboard. Accordingly, what is the perimeter of the orange cardboard in Figure 1 in cm? A) 46 B) 54 C) 66 D) 82 E) 104
