To get to the answer, we'll have to multiply the pieces of mail delivered each second by the amount of seconds in 6 days. This is,


\begin{gathered} (2^4*3*5^3)*(2^8*3^4*5^2)^{} \\ \rightarrow2^4*3*5^3*2^8*3^4*5^2^{} \end{gathered}

Using power properties,


2^4*3*5^3*2^8*3^4*5^2\rightarrow2^(12)*3^5*5^5

Therefore,


2^(12)*3^5*5^5

pieces of mail are delivered by the United States Postal Service in 6 days.
