MATLAB: Calculating the volume inside an arbitrary closed surface

closed areanumerical calculationvolume

Hi all I want to calculate the interior volume of a closed area. the aria is limited to: -l<x<l , -l<y<l , 0 < z < f(x,y) Could one help me??

MATLAB: Help using sub functions

function Options=NV_hw2_4(volume,price) %goal here is to use the surface areas from the subfunctions and multiply them by the price which will be an input in the main function 
  cubeSA= getSA1(volume) ; 
  cylinderSA= getSA2(volume) ; 
  sphereSA= getSA3(volume) ; 
SAS= [cubeSA,cylinderSA,sphereSA] ;
Options= price.*SAS
end
function cubeSA= getSA1(volume) %this function finds the surface area of a cube based on volume
g=nthroot(volume,3) %solving for the side length and assigning it to g
cubeSA=6*g^2 % calculating surface area based off the side length (g)
end
function cylinderSA= getSA2(volume) %this finds SA of the cylinder based on volume
c= nthroot((volume/pi),3) %finding the radius required
cylinderSA= (2*pi*c^2)*2 %calculating surface area with the required radius to match the desired volume
end
function sphereSA= getSA3(volume) %this funds the SA of the sphere
d= nthroot((volume/((4/3)*pi)),3) %solving for the required radius 
sphereSA= (4*pi*d^2)%calculating the surface area with the required radius for the desired volume
end

Run like this:

volume = 10 ; 
price = 5 ; 
options = NV_hw2_4(volume,price) ;
