What is the equation for computation of volume by prismoidal formula?
V = (D/2)(A1 + A2 + A3 + ........ + An - 1 + An)
V = (D/2)(A1 + An) + 2(A2 + A3 + ........ + An - 1)
V = (D/3)(A1 + An) + 2(A3 + A5 + ........ + An - 1) + 4(A2 + A4 + ........ + An - 2))
V = (D/2)(A1 + A2 + A3 + ........................ + An - 1 + An)
