Packing 2 boxes of chocolate into a large box can reduce the area of two faces
to minimize the packaging paper, the reduced area should be maximum = 12 × 8 = 96 square centimeters
, so 2 boxes of chocolate force After stacking
long = 12, width = 8, height = 3 × 2 = 6
The surface area = (12 8) × 2 × 6 12 × 8 × 2 = 432 square centimeters
So so , Xiaoya needs at least 432 square centimeters of packaging paper
