The volume of a neutron is about $10^{-45} \mathrm{m}^{3}$. Suppose you packed the number of neutrons you found in problem 2 into a sphere of radius $R$. The volume of a sphere is $4 / 3 \pi R^{3}$. What is $R$ in kilometers?

Key Concepts

Spherical Volume Formula

This concept involves using the formula V = (4/3)?R³ to determine the volume of a sphere given its radius. Understanding this relationship is crucial for reverse-engineering the radius from a known volume, which is central to solving problems where the volume is derived from a collection of objects, such as packed particles.

Unit Conversion

Unit conversion is the process of converting a measurement from one unit to another, such as meters to kilometers. In problems that bridge microscopic scales and macroscopic measurements, correctly converting units ensures that the final answer is expressed in the desired scale, which is essential for clarity and accuracy.

Exponent Arithmetic and Scientific Notation

Scientific notation is used to express very large or very small numbers in a convenient form, while exponent arithmetic governs the operations performed on these numbers. Mastering these techniques is vital for handling the extreme scales encountered in physical problems, such as calculating volumes and radii when dealing with subatomic particles.
