To calculate the magnification, you need to divide the size of the image (how big the object appears under the microscope) by the actual size of the object.

First, you need to make sure both measurements are in the same units. In this case, the woodlouse's actual size is given in millimeters (mm) and the size under the microscope is given in centimeters (cm). There are 10 millimeters in 1 centimeter, so you need to convert the size under the microscope from centimeters to millimeters.

12 cm = 120 mm

Now, you can calculate the magnification:

Magnification = Size of image / Actual size of object

Magnification = 120 mm / 8 mm

Magnification = 15

So, the magnification of the microscope is 15 times.
