The specific gravity of gold is 19.3. Write a MATLAB function that will determine the length of one side of a cube of solid gold, in units of inches, provided the mass of the cube in kilograms. The output should display a sentence like the one shown below, with the length formatted to 2 decimal places. If the user types a negative number or zero for the mass of the cube, your program should display an error message and terminate.
Sample Input / Output (multiple scenarios):
Enter the mass of the cube [kilograms]: -3
Error: Mass must be greater than zero grams.
Enter the mass of the cube [kilograms]: 0.4
The length of one side of the cube is 1.08 inches.

The code is written line wise with number. The code is explained by comments, which are written after % sign in bold. Note: Comments are not the part of code.

Explanation:

1. mass = input('Enter the mass of cube [kilograms]:'); %First we take mass input and save in variable m

2. if mass <= 0 %Condition for value less than or equal to 0

3. disp('Mass must be greater than zero grams');

4. end

5. if mass > 0

6. density = 19.3*1000; % Calculating Density of gold

7. Volume = mass/density; %Calculating Volume

8. Length = Volume^(1/3); %Calculating Length of edge

9. Length = Length*(39.37); %Conversion to inches

10. fprintf('The length of one side of cube is ');

11. fprintf('%.2f',Length);

12. fprintf(' inches');

13. end
