v = lwh which equation s best represents the remaining units when justifying your rearrangement to solve for the width

1 answer

To rearrange the equation for volume \( V = lwh \) to solve for the width \( w \), you would isolate \( w \) on one side of the equation. Here’s how you can do that:

  1. Start with the original equation: \[ V = lwh \]

  2. To solve for \( w \), divide both sides by \( lh \): \[ w = \frac{V}{lh} \]

In this rearrangement, you've expressed the width \( w \) in terms of the volume \( V \), length \( l \), and height \( h \).

When justifying the rearrangement, you may want to mention the units involved:

  • The unit for volume \( V \) is typically cubic meters (m³).
  • The unit for length \( l \) is meters (m).
  • The unit for height \( h \) is also meters (m).

Thus, when you divide \( V \) by \( lh \), the units would be: \[ \text{Units of } w = \frac{\text{m}^3}{\text{m} \cdot \text{m}} = \frac{\text{m}^3}{\text{m}^2} = \text{m} \]

This confirms that the resulting unit for \( w \) is consistent with its physical interpretation as a width, which is measured in meters.
