Answer 1

✨Answer:

The length of longest pole is 12 m.

✨ Step-by-step explanation:

Longest pole can be placed diagonally.

➡️ Room is cuboid.

➡️ Diagonal of cuboid

= sqrt l^2 + b^2 + h^2

= sqrt 8^2 + 8^2 + 4^2

= sqrt 64 + 64 + 16

= sqrt 128 + 16

= sqrt 144

= 12 m.

Length of longest pole that can be placed is 12 m.
