What is the equation for computation of volume by prismoidal formula?
1
\(V = \frac{D}{2}\left[ {{A_1} + {A_2} + {A_3} + ..... + {A_{n - 1}} + {A_n}} \right]\)
2
\(V = \frac{D}{2}\left[ ({{A_1} + {A_n} )+ 2\left( {{A_2} + {A_3} + ..... + {A_{n - 1}}} \right)} \right]\)
3
\(V = \frac{D}{3}\left[ {({A_1} + {A_n}) + 2({A_3} + {A_5} + .....{A_{n - 1}}) + 4({A_2} + {A_4} + .....{A_{n - 2}})} \right]\)
4
\(V = \frac{D}{2}\left[ {{A_1} + {A_2} + {A_3} + ..... + {A_{(n - 1)}} + {A_n}} \right]\)
