Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 125000 cm³.

The length of the longest rod that can be placed in the cubical room, which is the space diagonal of the cube

Diagonal = 3\sqrt3a

where, a = side of the cube

⇒ a = 50 cm

Volume of the cube = a3

Volume = 503 = 125000 cm3
