A metallic cubical box was hammered and moulded into a rectangular box such that the only change was that the breadth got tripled. What was the percentage change in total surface area?
Although the scenario is too hypothetical to think of, wherein just one side of the new cuboid has tripled after hammering and everything else remains unchanged, yet considering the hypothesis to be real the answer goes as below.
Tripling one side of the cuboid the surface area becomes 14x of the original surface area 6x.

Tripling one side of the cuboid the volume become 3x of the original volume x.
Hi the question stem asks % change in surface area.
