Step by step explanation

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
