Determine appropriate bottle size

To package a volume of approximately \(6.67\text{ oz}\), the container must be larger than this volume. Standard prescription bottle sizes are \(2\text{ oz}\), \(4\text{ oz}\), \(6\text{ oz}\), and \(8\text{ oz}\). A \(6\text{ oz}\) bottle holds up to \(180\text{ mL}\), which is insufficient. Therefore, the next standard size up must be used, which is an \(8\text{ oz}\) bottle.

Answer:

• The original packaging.
• A 4-oz prescription bottle.
• A 6-oz prescription bottle.
• An 8-oz prescription bottle. (Correct answer)
