I bough wooden logs (not the chocks, sorry) and want to check the total volume of wood (m³).
I measured top perimeter length (circumference), bottom perimeter length and length of the even log.
The log section isn't always looks like a perfect circle, sometimes it's have an oval shape or a complex shape, but never curved inside.
So i have a three numbers in cm: 67, 68, 38. I entered all the data to spreadsheet and stuck with the right formula.
What the formula to find the volume of the even log?
