Question

A box is 21 centimeters tall How tall would the box measure in meters Enter your answer in the box​

Answer 1

`0.21\ m`

Explanation:

Let's set up a unit converter:

(Please note that 1 m = 100 cm OR 1 cm =
`10^(-2)` m)

`21\ cm((10^-2\ m)/(1\ cm))`

The "cm" cancel out leaving us with:

`21*10^(-2)\ m=0.21\ m`
