Answer 2

Answer:

The displacement of fly would be 17.32 m

Explanation:

A hall has the dimensions 10 m x 10 m x 10 m.

The shape of room like cube because all the three sides are same.

A fly starting from one corner and ends up a body diagonal opposite corner.

The displacement of fly is length of body diagonal of cube.

using formula:

$\text{Length of body diagonal }=\sqrt3a$

where, a is side of cube.

Here, a = 10 m

Thus, Displacement of fly $=\sqrt{3}\cdot 10$

                                          $=10\sqrt{3}\text{ m}\approx 17.32\text{ m}$

Hence, The displacement of fly would be 17.32 m
