Hi .

.

.

hi u made it your weird .

Each length would be multiplied by 2, meaning the volume itsself would also be multiplied by 2.

So the Answer is A, "The new volume is two time the old volume."

Step-by-step explanation:

It wouldn't make sense to add each length and make it 8 because thats not how you find volume. To find volume is leangth X width X height, so your length would only be mulitplied by 2, which does the same to your volume.
