The answer is option A

Evan Pollard · Answer 2

The answer should be A

original volume = Area x Height

If the the height was increased by a factor of 3,

Volume = Area x (Height x 3)

Which ultimately still means

Volume = (Area x Height) x 3

Which gives you the answer

Volume = (original volume) x 3

That's why the answer is A as the volume increased by a factor of 3
