Find the total mass of a mass distribution of densityσin a regionTin space.

$\displaystyle \sigma = 1 + y + z^2$, T the cylinder $\displaystyle y^2 + z^2 \leq\ 9, 1\leq x\leq 13$

$\displaystyle \int\int\int _{T}\sigma dxdydz$

I'm pretty sure I know how to integrate it but I am not sure how to get the upper and lower limits for dy and dz
