Answer:

  • Yes
  • 210 cm² left over

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:

  • 5500 - 5290 = 210 cm²
