Answer 1

Answer:

4.2925 m² paper is required.

Step-by-step explanation:

Surface area of a box = 22*11 + 11*3 + 3*22 = 242+33+66 = 341 cm²

Each box require 164 cm² more for folding.

So, area of paper required for one box = 341 + 164 = 505 cm²

Area of paper required to cover 85 boxes = 85*505 = 42,925 cm²

= 4.2925 m²
