Answer 2

Step-by-step explanation:

Dimensions of Rectangular Box

• Length l = 30 cm
• breadth b = 20 cm
• height h = 109 cm

Cloth required to cover = total surface area of the box

• Total surface area of box (cuboid) = 2 (lb + bh + lh)
• = 2 (30×20 + 20×109 + 109×30)
• = 2 (600 + 2180 + 3270)
• = 2 × 6050
• = 12100 cm² or 121 m²
