![Q=\int\limits^2_{x=0} {x^2} \, dx \int\limits^2_{y=0} {y} \, dy \int\limits^2_{z=0} {e^{-z}} \, dz \\\\Q=(\frac{1}{3} [x^3]^2_0)(\frac{1}{2} [y^2]^2_0)(-1 [e^{-z}]^2_0)\\\\Q=\frac{-1}{6} ([x^3]^2_0)( [y^2]^2_0)( [e^{-z}]^2_0)\\\\Q=\frac{-1}{6}[2^3-0^3][2^2-0^2][e^{-2}-e^0]\\\\Q=\frac{-1}{6}(8)(4)(0.1353-1)=\frac{-1}{6}(8)(4)(-0.8647)\\\\Q=4.61\ mC](/tpl/images/0698/6251/15d4a.png)
