## Estimating and Costing The correct Prismoidal formula for volume is

D [first area + last area + Ʃ Even area + 2 Ʃ odd areas]
D/3 [first area + last area + 4 Ʃ Even area + 2 Ʃ odd areas]
D/3 [first area + last area + 2 Ʃ Even area + 4 Ʃ odd areas]
D/6 [first area + last area + 2 ∑ Even area + 4 ∑ odd areas]
