Answer:
Minimum 2 rolls will be required.
Step-by-step explanation:
Surface area of all three boxes = Area of the wrapping paper required
Surface area of Box 1 = 2(lb + bh + hl)
= 2(8.5×14.5 + 14.5×1.5 + 8.5×1.5)
= 315.5 square inches
Surface area of box 2 = 2(9.5×14.5 + 14.5×2 + 9.5×2)
= 371.5 square inches
Surface area of box 3 = 2(15.5×12 + 12×4 + 15.5×4)
= 592 square inches
Surface area of box 4 = 2(11×16 + 16×3 + 11×3)
= 514 square inches
Total surface area = 315.5 + 371.5 + 592 + 514
= 1793 square inches
Dimensions of the wrapping paper = 30" × 9 feet Or 30" × 108"
Area of the wrapping paper = 3240 square inches
Number of papers required to wrap all four boxes = [tex]\frac{3240}{1793}=1.8[/tex]
≈ 2 rolls
Therefore, minimum 2 rolls will be required to wrap the presents.
