Question Analysis:
This question involves calculating the surface area of one rectangular prism and dividing the total available paper area to see how many full boxes can be wrapped.
The main focus is on applying division with surface area for maximum quantity.

Key Concept Explanation:
Surface Area of one box = 2(lw + lh + wh)
Paper area = 40 in × 30 in
Max number of boxes = total paper area ÷ surface area per box
Use floor division since partial boxes can't be wrapped.

Step-by-Step Solution:
Box Surface Area:
lw = 12 × 10 = 120
lh = 12 × 6 = 72
wh = 10 × 6 = 60
→ Total = 120 + 72 + 60 = 252
→ 2 × 252 = 504 in² per box
Wrapping Paper Area:
40 in × 30 in = 1,200 in²
Maxim...
