One atomic mass unit is defined as 1.66 x 10^-27 kg. If a proton has a mass of one atomic mass unit and a density of approximately 5.8 x 10^27 kg/m3^ . What is the diameter of a proton if we assume it is a sphere?

The diameter is

Explanation:

From the question we are told that

   The value of one atomic mass unit is

    The density of the proton is  

Generally the volume of the proton (sphere)is mathematically represented as

Generally this volume can also be evaluated as

=>    

=>  

So

=>  

=>  

Now the diameter is mathematically represented as

=>

=>

i don't understand. explain it clearly
