  • Leteral Surface Area of cuboid is 2h ( l + b )

⇒ 2 × 20 ( 40 + 30 )

⇒ 40 × 70

= 2800 cm²

  • Now we find Total Surface Area of cuboid

So,

T.S.A of cuboid = 2 (lb + bh + hl )

where length = 40cm, breadth =30 cm

and Height = 20cm

⇒ 2 (lb + bh + hl)

⇒ 2 (40 × 30) + (30 × 20) + (20 × 40)

⇒ 2 (1200) + (600) + (800)

⇒ 2 (2600)

= 5200 cm²
