Answer:
The volume would double.
Here is an example:
The formula for the volume of a cylinder is:
V = (area of the base) x height
Now, let's plug in numbers to see what happens to the volume:
Let's say that cylinder 1 has a base area of 6 and a height of 10. Cylinder 2 would have a base area of 6 and a height of 20.
Let's plug in the values:
V1 = 6x10 = 60
V2 = 6x20 = 120
the volume doubles.
hope this helps :)
