Answer:
3.5cm
Step-by-step explanation:
Please see attached picture for full solution.
Volume of cylinder= πr²h, where r is the radius and h is the height.
Volume of a rectangular solid is lwh
Increase of 5% make the volume to be 1.05l(1.05w)(1.05)h = 1.157625lwh
which is approximately an increase of 15.8% of the original volume.
