If the edge of a cube is tripled, then its volume increases to _______ times its original volume.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 27.
Let the original cube’s edge length be a.
Original volume = a3
New edge length (tripled) = 3a
New volume = (3a)3 = 27
So the new volume is 27 times the original volume.
