Question

# Calculate the LSA of a cuboid of ,length = 40cm ,breadth = 20cm and height = 10cm.

- 300
- 600
- 400
- 1200

Hint:

### Lateral Surface Area (LSA) of cuboid = 2h( l + b)

where

l → length of the cuboid

b → breadth of the cuboid

h → height of the cuboid

## The correct answer is: 1200

- We are given the dimensions of cuboid.

length = 40cm = l

breadth = 20cm = b

height = 10cm = h

- We will calculate the LSA of given cuboid

We know that,

The Lateral Surface area of cuboid = 2h( l + b)

- By using the above formula of the lateral surface area of the cuboid, we get

The lateral surface area of the given cuboid is,

= 2h( l + b)

= 2 10 (40 + 20)

= 20 (60)

LSA= 1200 cm^{2}

Therefore the Lateral surface area of the given cuboid is 1200 cm^{2}.

The correct answer is option d) 1200.

^{2}

Therefore the Lateral surface area of the given cuboid is 1200 cm

^{2}.

The correct answer is option d) 1200.
