Question 34
What happens to the volume (V) of the cuboid. if its length is doubled. height is doubled and breadth is kept the same?
Solution
Let length, breadth and height be L, B and H resp.
Let original Volume be $$V = L\times B\times H =LBH $$
New Volume $$= V1 = 2L\times B\times 2H = 4LBH =4V $$
$$\frac{New Volume}{original Volume} = \frac{4LBH}{LBH} $$
$$V1 = 4V$$
Option C is correct.
