$\mathrm{V}-\mathrm{V}_{(0,0,0)}=\int_{0}^{1} \mathrm{E}_{\mathrm{x}} \mathrm{d} \mathrm{x}+\int_{0}^{1} \mathrm{E}_{\mathrm{y}} \mathrm{d} \mathrm{y}$
$\mathrm{V}-2=\left[\mathrm{x}^{2}\right]_{0}^{1}+\frac{1}{3}\left[\mathrm{y}^{3}\right]_{0}^{1}$
$\mathrm{V}=2+1+\frac{1}{3}=\frac{10}{3} \mathrm{\,volt}$
