Given Length of Cuboid = 12cm
Given Breadth of Cuboid = 9cm
Given height of Cuboid = 8cm
Total Surface area of cuboid = 2(lb + bh + hl)
where, l stands for legth of the cuboid, b stands for breadth of the cuboid and h stands for height of the cuboid.
Put the given values of l,b and h in the formula
=> Total surface area of cuboid = 2((12×9)+(9×8)+(8×12))
=> 2(108 + 72 + 96)
=> 2(180 + 96)
=> 2 × 276
=> 552 sq. cm is the total surface area of cuboid

TSA of cuboid = 2 (lb +bh +lh)
=2 (12×9+9×8+8×12)
= 2(72+108+96)
=2(276)
=552 sq cm
hope it helps you
