pshichka [43]
The face of the tetrahedron in the first octant, not coinciding with any of the planes generated by the coordinate axes, is given by the plane x+y+z=0. So the integral can be set up as

\displaystyle\iiint_{\mathcal T}5x^2\,\mathrm dV=\int_{x=0}^{x=1}\int_{y=0}^{y=1-x}\int_{z=0}^{z=1-x-y}5x^2\,\mathrm dz\,\mathrm dy\,\mathrm dx=\frac1{12}
