What will be the volume (V) of the cuboid, if its length is doubled, height is halved and breadth is tripled?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 3V.
Let original length = l, breadth = b, height = h
Original volume = l × b × h
New length = 2l
New height = h/2
New breadth = 3b
New volume = (2l) × (3b) × (h/2) = 3 × (l × b × h)
So, new volume V = 3V
