Step-by-step explanation:
Lenght-80cm
Breadth-40cm
Height-20cm
We have to find the area of CUBOIDAL box
-Area of CUBOID-2(lb+bh+hl)
PUT THE VALUES IN THE FORMULA
=2(80×40+40×20+20×80)
=2(3200+800+1600)
=2(5600)
=11,200 cm sq
Therefore Area of box =11,200cm sq
NOW WE WILL FIND THE SHEETS REQUIRED
Square sheets required= Area of box÷square sheets of 40cm
=11,200÷40
=280 SHEETS
THEREFORE SHEETS REQUIRED ARE 280.
