Question

find the lateral surface area of a cuboid of length 40 cm, breadth 27cm and height 10 cm ​

Answer 1

Answer:

Step-by-step explanation:

Lsa of cuboid = 2(l+ b )h

= 2(40 + 27) 10

= 2 × 67 × 10

1340 cm²

Answer 2

Given: Length of cuboid is 40cm, breadth of cuboid is 27cm, and height is 10cm.

To find: The lateral surface area of the cuboid.

Solution:-

As per the provided information in the given question, we are given that,

• Length, l = 40cm
• Breadth, b = 27cm
• Height, h = 10cm

And we need to find the lateral surface area (LSA) of a cuboid.

We know the lateral surface area of a cuboid of length l, breadth b, and height h is given by,

• LSA of Cuboid= 2h(l + b)

By substituting the known values in the formula, we get the following results:

⇒ LSA = 2 * 10(40 + 27)

⇒ LSA = 20(40 + 27)

⇒ LSA = 20(67)

⇒ LSA = 1340

Hence, the lateral surface area of a cuboid is 1340cm².
