Question

What is the length of the paintbrush in centimeters? (162mm)

Answer 1

The first thing is to find the equivalence between millimeters and centimeters.

1 cm = 10 mm, therefore:

$162\operatorname{mm}=\frac{1\operatorname{cm}}{10\operatorname{mm}}=16.2\operatorname{cm}$

The paintbrush measure 16.2 cm
