Identify the INCORRECT statement regarding the prismoidal formula used to compute earthwork volume.
- 1Prismoidal formula is also known as Simpson's rule for volume.
- 2If there is an even number of cross-sections, the end strip must be treated separately, and the volume between the remaining sections may be calculated by the prismoidal formula.
- 3It is necessary to have an odd number of cross-sections to apply the prismoidal formula directly.
- 4The ratio of volume calculated by the end area formula and the prismoidal formula is defined as the 'Prismoidal correction'.✓
Correct answer
The ratio of volume calculated by the end area formula and the prismoidal formula is defined as the 'Prismoidal correction'.
