20 m​

Answer 1

Appropriate Question:-

• Find the lateral surface area of a Cuboid whose length is 70 cm breath is 30 cm and height is 20 m.

━━━━━━━━━━━━━━━━━━━━━━━━━

Given:-

• Length of Cuboid = 70 cm

• Breadth of Cuboid = 30 cm

• Height of Cuboid = 20 cm

To Find:-

• Lateral Surface Area of Cuboid

Formula Used:-

• ${\boxed{\bf{LSA\:of\: Cuboid=2h(l+b)}}}$

Solution:-

Using Formula,

$\sf :\implies\:LSA\:of\: Cuboid=2h(l+b)$

$\sf :\implies\:LSA\:of\: Cuboid=2\times20(70+30)$

$\sf :\implies\:LSA\:of\: Cuboid=40\times100$

$\bf :\implies\:LSA\:of\: Cuboid=4,000\:cm^2$

Hence, The Lateral Surface Area of Cuboid is 4,000cm²

━━━━━━━━━━━━━━━━━━━━━━━━━

More Formulas for Cuboid:-

• $\bf TSA\:of\: Cuboid=2(lb+bh+hl)$

• $\bf Volume\:of\: Cuboid=l\times b\times h$

Answer 2

Given, Dimensions of a cuboid :

• Length (l) = 70 cm
• Breadth (b) = 30 cm
• Height (h) = 20 cm

We know that,

• Lateral Surface Area = 2 [l + b]h

Now,

= 2 [70 + 30] 20

= 40 [100]

= 4000

Thus,

• Lateral Surface Area is 4000 cm².
