Answer 1

Hope it will help you...

Answer 2

Answer:

Step-by-step explanation:

Length of a cuboid (l)=1cm

⇒  Breadth of a cuboid (b)=4cm

⇒  Height of a cuboid (h)=8cm

Total surface area of cuboid =2(lb+bh+hl)

⇒ 2 ( 1×4 + 4×8 + 1×8 )

⇒ 2 ( 4 + 32 + 8 )

⇒ 2 ( 44 )

⇒ 88 cm is Total Surface area of Cuboid

lateral surface area of cuboid = 2h ( l+b )

⇒ 2 × 8 ( 1+4 )

⇒ 16 × 5

70 is the curved surface area or lateral surface area of cuboid.
