Question

In a cuboid if the length is doubled, height is tripled and breadth remains constant, then how many times does the volume becomes of its initial volume?

• A. 6
• B. 4
• C. 5
• D. 8

Answer 1

The correct option is A 6

Let, the initial length, breadth and height of the cuboid be 'l', 'b' and 'h' respectively.
Volume of initial cuboid = lbh ....(i)

length of the cuboid after change = 2l
breadth of the cuboid after change = b
height of the cuboid after change = 3h
Volume of the cuboid after change = 6lbh ....(ii)
$\therefore$ Volume of cuboid changes by 6 times.
