# Get all integration orders and plot them?

GROUPS:
 Hello, I just downloaded Wolfram Mathematica and would like to know how to plot and get the integration limits in all orders. I know it can be done because I saw someone doing it in college and he was using Mathematica, probably an older version though. The volume described by the integrals are not defined using functions but as the sort: I went through the references and guides and could find regionplot3D function and others similar but all of them need the range for x,y and z. I'd like to be able to put the inequalities such as in the image and get all 6 possibles integrals to calculate. I don't know if i'm being clear :sAlso can I use wolfram cloud on my phone using the college's license? I tried to but apparently I have to pay for mathematica online (and app therefore). Can this (what I'm asking) be done in wolfram alpha or Matlab?Thanks and excuse my english
 Perhaps Integrate[1, {x, 0, 1}, {z, 0, x}, {y, x/2, x}] 
 This doesn't answer your question, but here is one way to just type in the inequalities and have Mathematica plot and integrate: region = ImplicitRegion[x/2 <= y <= x && 0 <= z <= x && x <= 1, {x, y, z}]; DiscretizeRegion[region] Integrate[1, {x, y, z} \[Element] region]
