Step-by-step explanation:

Points to remember:-

Surface area of cuboid

Surface area = 2(lb + bh + lh)

Where, l - Length of cuboid

b - Breadth of cuboid and

h - Height of cuboid

It is given dimensions of cardboard box

12 cm long, 9 cm wide, and 9 cm high.

To find the surface area of box

Here l = 12 cm, b = 9 cm and h = 9 cm

Surface area = 2(lb + bh + lh) = 2[(9*12) + (9*9) + (12 * 9)]

 = 2(108 + 81 + 108) = 2 * 297 = 594 square cm

To find the cardboard required for 1500 box

Total cardboard = 1500 * 594 = 891000 square cm
