Given:

The statement, $40\text{ m}=\underset{¯}{?}\text{ cm}$ .

Concept Used:

The conversion factor, $1\text{ m}=100\text{ cm}$ .

Calculation:

In order to complete the given statement $40\text{ m}=\underset{¯}{?}\text{ cm}$ , use the conversion factor $1\text{ m}=100\text{ cm}$ and simplify further as shown below

  $\begin{array}{c}40\text{ m}=40\times 100\text{ cm}\\ =4000\text{ cm}\end{array}$
