Question

find the maximum length of a rod with negligible thickness which can be fitted into a cubical box of 1 meter length of each side.?who give answer faster......

Answer 1

We have to find the length of the diagonal of the cube=root 3 a1
$\sqrt{3 \times a {1}^{2} }$
Root 3(1)
Root 3 meters

Answer 2

The maximum length is the one that can go diagonally into the box.

Find the diagonal length of the base:

Length of the box = 1 m

Breath of the box = 1 m

a² + b² = c²

c² = 1² + 1²

c² = 2

c = √2 m

Find the diagonal length of the box:

Length = 1 m

Diagonal length of the base = √2

a² + b² = c²

c² = 1² + (√2)²

c² = 1 + 2

c² = 3

c = √3 m

Answer: The max length of the rod that can go into the box is √3 m
