Answer 2

Answer:

ANSWER FOR YOUR QUESTION IS 552 SQUARE CM

Step-by-step explanation:

Given length of cuboid = 12 cm

Given length of cuboid = 9cm

Given length of cuboid = 8cm

Total surface area of cuboid = 2[ LB+BH+HL ]

PUT THE GIVEN VALUES OF L,B,AND H IN THE FORMULA

⇒ Total surface area of cuboid = 2[12x9 + 9x8 + 8x12 ]

⇒2[108+72+96]

⇒2 [ 180 = 96 ]

⇒ 2x 276

⇒552

∴therefore , 552 square cm is the total surface area of a cuboid
