- Cylinder
- Paraboloid – Smalian’s formula & Huber’s formula
- Cone
- Neiloid – Newton’s formula or Prismoidal formula
where,
s is the sectional area at the base in square units
s1 is the sectional area at the thick end in square unitssmis the sectional area at the middle in square units
s2 is the sectional area at the thin end in square units
l is the length of the log or height of the solid in linear units
