Answer 1

The length of the plank in cm is 113.375 cm

Length of the plank in inches = 45.35 inches

You were asked to convert 45.35 inches to centimeters

Let x represents the converted length in cm

Recall that, 1 inch is equivalent to 2.5 centimeters according to the Standard International unit

The next step is to convert the length to cm

`\begin{gathered} 1\text{ inch }\rightarrow\text{ 2.5 cm} \\ 45.35\text{ inches }\rightarrow\text{ x cm} \\ \text{Cross multiply} \\ 1\cdot\text{ x = 2.5 }\cdot\text{ 45.35} \\ x\text{ = 113.375 cm} \end{gathered}`

Therefore, the length of the plank in cm is 113.375 cm
