Question

Five cubes each of edge 2 cm are joined face to face. The surface area of the cuboid thus formed is :​

Answer 1

Answer:

Side of each cube = 2cm

Five cubes are joined end to end, then length of newly formed cuboid = 2 × 5 = 10 cm

Breadth of newly formed cuboid = 2 cm

Height of newly formed cuboid = 2cm

As we know,

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

⇒ 2 (10 × 2 + 2 × 2 + 2 × 10)

⇒ 2 (20+4+20)

⇒ 2 × 44

⇒ 88 cm2

Answer 2

Answer:

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

2(10×2+2×2+2×10)

2(20+4+20)

44cm^3
