A laboratory technician checks a light microscope. With a ×12 \times12\,×12 eyepiece lens and one objective lens, the total magnification is ×240\times240×240.
The technician keeps the same objective lens but replaces the eyepiece lens with a ×15 \times15\,×15 eyepiece lens.
Calculate the new total magnification.
