Explanation:

Step1: Recall volume formula

The volume formula for a rectangular - prism is $V = lwh$, where $V$ is volume, $l$ is length, $w$ is width, and $h$ is height.

Step2: Rearrange formula for width

We want to find $w$, so we can rewrite the formula as $w=\frac{V}{lh}$.

Step3: Substitute given values

Given $V = 200m^{3}$, $l = 10m$, and $h = 5m$. Substitute these values into the formula: $w=\frac{200}{10\times5}$.

Step4: Calculate width

First, calculate the denominator $10\times5 = 50$. Then, $\frac{200}{50}=4$.
