Question

If l=5cm, b=2cm, h=10cm, then find the curved surface area of cuboid.​

Answer 1

Step-by-step explanation:

Curved surface area of cuboid

$= 2(l \times b + l \times h + b \times h) \: sq.unit$

$= 2(5 \times 2 + 5 \times 10 + 2 \times 10) \: \: sq.cm$

$= 2(10 + 50 + 20) \: \: sq.cm$

$= 2 \times 80 \: \: sq.cm$

$= 160 \: \: sq.cm$

Answer :- Curved Surface area of cuboid is 160 sq. cm

Answer 2

Given :

⬤ Length of Cuboid = 5 cm .

⬤ Breadth of Cuboid = 2 cm .

⬤ Height of Cuboid = 20 cm .

To Find :

⬤ Curved Surface Area of Cuboid .

Formula Used :

$\sf[\:{Curved\:Surface\:Area\:of\:Cuboid=2h(l+b)}\:]$

• h = Height
• l = Length
• b = Breadth

Solution :

According to the Formula :

2h (l + b)

2 × 20 (5 + 2)

40 (7)

280

Therefore , The Curved Surface Area of Cuboid is 280 cm² .

Related Formulas :

• Curved Surface Area of Cuboid = 2h (l + b)
• Surface Area of Cuboid = 2 (lb + bh + hl)
• Volume of Cuboid = l × b × h
• Volume of Cylinder = πr²h
• Curved surface area of Cylinder = 2πrh
• Surface Area of Cylinder = 2πr (r + h)
• Surface Area of Cube = 6a²
• Volume of a Cube = a³
