A student views a cheek cell through a microscope. The scale is 1cm=10 micrometers

A)use the scale given to calculate the magnification
B)deduce the size of a cheek cell

I have worked out that the size of the cheek cell is 3cm.
Please help me as I’m struggling

magnification = image size / object size

30 micrometers = 0.003cm

3/0.003 = 1000

Object size = image size/magnifcation

3/1000 = 0.003cm

= 30 micrometers / 0.003cm

Thank you! You really helped me!
