Need help with user made Functions and Sub functions.

Create a function that finds the volume, surface area and perimeter of a rectangular prism of height h, width w and depth d.

It should use separate sub functions to calculate the volume, surface area and the perimeter. The main function should be called and three arguments should be passed as such: function_name(h,w,d).

I have this so far, but I need help. If anybody can help or point me in the right direction, it would be much appreciated. Thank you.

The assignment operations were not right, and have rectified the code. The invoking format was also not correct, as you require three arguments and the one you provided was a single variable with four values.

function [v,sa,p] = Rectangle(w,h,d)
v = volume(w,h,d);
sa = surface_area(w, h, d);
p = perimeter(w, h, d);

function v = volume(w, h, d) 
v = w*h*d;

function sa = surface_area(w, h, d)
sa = 2*(w*d+h*d+h*w); 

function p = perimeter(w, h, d) 
p = 2*d + 2*w; 

%to run the function use [v,sa,p] = Rectangle(1,2,3)
