hey mate jere is ur answer
given that
length = l = 80 cm
breadth = b = 40 cm
height = h = 20 cm
to find
TSA of box = 2( lb + bh + hl)
= 2 ( 80×40 + 40×20 + 20×80)
= 2 ( 3200 + 800 + 1600 )
= 2 ( 5600 )
= 11200 cm ^2
area of a square sheet = side^2
= 40^2
= 1600 cm^2
no of sheets required
ar (cuboidal box) / ar (square sheet)
11200/1600
= 7 sheets
hence 7 sheets are required to cover the box
