Use Matlab

For matrix $A=\left[\begin{array}{ccc}1& 20& 56\\ 2& 23& 54\\ 3& 21& 57\end{array}\right],$ if the first column is the part's serial number,

the second column represents the mass of the parts, the third column is the

density, calculate the volume of each part, and a total volume of all parts. Fill the

total volume in the blank. Keep $4$ digits after decimal point. $($hint: Volume $=$ Mass $/$

density$)$

Total volume $=$
