hello friend
Let V is equal to 0 i.e
2 {x}^{2}   - 16 = 0 \\   { (\sqrt{2x})  }^{2}  -  {4}^{2}  = 0 \\ ( \sqrt{2x}  + 4)( \sqrt{2x}  - 4) = 0 \\ ( \sqrt{2x} + 4)(( { \sqrt[4]{2x}) }^{2}   -  {2}^{2} ) = 0 \\ ( \sqrt{2x }  + 4)( \sqrt[4]{2x}  - 2)( \sqrt[4]{2x} + 2) = 0
those 3 factors represent dimensions..
Hope it helps ..
