Question

# Given LSA of a cuboid is 900cm^{2 }and the breadth x length are 10cm x 20cm.Calculate height of cuboid.

- 15
- 12
- 10
- 20

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: 15

- We have given,

LSA of cuboid = 900cm^{2}

Breadth= 10 cm

Length = 20 cm

- We know that ,

LSA of cuboid = 2h( l + b)

- Insert the values in the above equation.

900 = 2h (20 + 10)

900 = 2h(30)

Divide both sides of equation by 30, we get

Divide both sides of equation by 2, we get

h = 15

- Therefore the height of given cuboid is 15 cm.
- The correct option is option a) 15 .

Divide both sides of equation by 30, we get

Divide both sides of equation by 2, we get
