Question

# What is the length of the longest pole that can be fit in the room of dimensions 5m x 10m x 5m

- 12.25
- 11.95
- 12.85
- 11.85

Hint:

### Diagonal of cube= × side = a unit

## The correct answer is: 12.25

### The dimensions of the room are

Length = 5m

Breadth = 10m

Height = 5m

We know that

Length of the longest pole = length of diagonal =

By substituting the values

Length of the longest pole =

So we get

Length of the longest pole =

By addition

Length of the longest pole =

Therefore, the length of the longest pole that can be put in the room is 12.25m.

The correct option is a)12.25.
