  "body": "\n## Summary\n\nThe Jordan measure, or Jordan content, extends the volume of boxes in [[R^n|0XPR1E85W0]] to some bounded sets. Finite unions of boxes approximate these sets well from inside and from outside.\nA bounded set has Jordan measure exactly when its indicator function is Riemann integrable, and then the measure is the integral of that function.\n",
