Answer 1

Answer:

100 cm of tape would be required .

Step-by-step explanation:

The sealing of tape would be the perimeter of the box .

Perimeter of the box (rectangular) = 2 × ( l + b )

Length of box = 40cm

Breadth of box = 10cm

2 × ( 40 + 10 )

= 2 × ( 50 )

= 100

Length of tape required is 100 cm .
