Answer:
Step-by-step explanation:
Find the full surface area of the cuboid:
- S = 2(lw + lh + wh)
- S = 2(20*25 + 20*40 + 25*40) = 4600 cm²
Add 15% to the area:
- 4600 + 15% =
- 4600*1.15 =
- 5290 cm²
Find the area of the paper and compare with the above number:
- A = 1 m * 0.55 m = 100 cm * 55 cm = 5500 cm²
The area of the paper is greater and the difference is:
