Questions and Answers

Which formula is the most accurate for calculating the volume of frustums of neiloid, paraboloid, and cone?

  • Newton's formula (correct)
  • Smalian's formula
  • Huber's formula
  • None of the above
  • Why is Newton's formula not widely used in practice for calculating the volume of logs?

  • It necessitates the measurement of the mid-diameter of logs when they are stacked.
  • It is difficult to apply when the logs are stacked and the mid-diameter cannot be measured. (correct)
  • It overestimates the volume of frustums of cylinders and paraboloids.
  • None of the above
