Answer 1

Hello mate..

Here Is Your Answer:

Length of the box = 80cm.

Breadth of the box = 40cm.

Height of the box = 20cm.

By, these dimensions we can conclude that the box is cuboid in shape.

Formula for finding area of a Cuboid = TSA = 2 (lb + bh + lh) square units.

TSA = 2 [ 80 (40) + 40 (20) + 20 (80) ]

TSA = 2 [ 5600 ]

TSA = 11,200 cm²

The area of each sheet paper = 40 × 40 cm² = 1600 cm²

Therefore,

No. of sheet papers required =

$\frac{surface \: area \: of \: box}{area \: of \: one \: sheet \: paper}$

$\frac{11200}{1600}$

= 7.

Therefore, No. of sheet paper required is 7.

HOPE THIS HELPS YOU OUT..
