Question

The length of the longest pole that can be placed in a room 3m long, 4m broad and 5m high is 12 m.

• A. True
• B. False

Answer 1

The correct option is B False

The length of the longest pole can be calculated by calculating the value of the diagonal of a room which is considered to be in the shape of a cuboid. Hence,

The Diagonal of the cuboid = $\sqrt{l^2+b^2+h^2}$
$\sqrt{3^2+4^2+5^2}=\sqrt{50}cm$
