# What will be the Maximum Length of Iron Rod? If

The Maximum length of Iron Rod that can be kept in a Room of Dimensions 10 cm x 8 cm x 6 cm is:

- 10 cm
- 10 sqrt. 2 cm
- 11 sqrt. 2 cm
- 12 cm

**Answer: (2) 10 sqrt.2**

**Explanation:-**

**Given-**

Dimensions of the room = 10 cm x 8 cm x 6 cm

**Formula-**

**The maximum length of rod that can be kept in a room = (length ^{2} + width^{2} + height^{2})^{1/2}**

Then, The maximum length of rod that can be kept in a room = (10

^{2}+ 8

^{2}+ 6

^{2})

^{1/2 }= (100 + 64 + 36)

^{1/2}

= (200)

^{1/2 }= 10 (2)

^{1/2}

Hence, the answer is (2) 10 sqrt.2.
