Thus area of the cardboard is 20600 cm^2
Explanation:
- Length of cardboard = 80 cm
- Breadth of cardboard = 70 cm
- Height of cardboard = 50 cm
Area of the cardboard = L.S.A of the box + Area of the box
Area of the cardboard = 2 h ( l + h ) + l x b
Area of the cardboard = 2 x 50 ( 80 + 70) + 80 x 70
Area of the cardboard = 100 x 150 + 5600
Area of the cardboard = 15000 + 5600
Area of the cardboard = 20600 cm^2
Thus area of the cardboard is 20600 cm^2
