Question from Justin: I have a pile of mulch that measures 19 feet wide at the bottom and has a height of 6 feet. I need to know how many yards of mulch I have. |
Hi Justin,
I assume that your pile is roughly cone shaped with a circular base with diameter 19 feet and height 6 feet.
Image from the San Diego Free Press
The volume of a cone is one third the volume of the cylinder with the same base and height.
Use our volume calculator to calculate the volume of a circular cylinder with base diameter 19 feet and height 6 feet and then take a third of the result to find the volume of the cone.
