Hey Buddy❤
Here's your Answer...
Given,
H = 20 cm , L = 80cm and B = 40cm.
Surface area of cuboidal box = 2( lb + bh + hl)
=> 2( 80×40 + 40 × 20 + 20×80)
=> 2( 3200 + 800 + 1600)
=> 2 × 5600
=> 11200cm^2.
Now,
Surface area of 1 square sheet = side^2
=> 40 × 40
=> 1600 cm^2.
Number of sheets required = 11200/1600
=> 7.
