Measure circumference at 4.5 from ground. Measure height by whatever method you want. There are several ways to do it. Take the height and multiply it by the circumference then divide by four. That gives the volume of the tree trunk minus the branches which can add a lot. When an ash tree is fully grown and leafed out the leaves alone can weigh as much as a ton (depending on hydration level). The branches account for about 800 - 1,000 pounds. So a 30 foot tall ash at about 50 pounds per cubic foot of volume in the trunk with a circumference of 6 feet will weigh 6ft x 30 / 4 = 2250 pounds plus the branches. That is minimal depending on the hydration level of the tree.

Volcanic ash is not heavy at all. which is why it is able to be carried by wind.
wood
Wood ash contain calcium carbonate, potassium compounds, phosphates, other metal oxides.
Ash is made from pulverized rock and glass created by volcanic eruptions.
wood
depending on size and what kind of wood ash wood is heavy
Ash wood is natural and comes from the Ash Tree (Fraxinus).
Maple is stronger than ash. Ash is still a very durable floor.
Volcanic ash is not heavy at all. which is why it is able to be carried by wind.
ash comes from the middle of the earth. that is why it's called ash it gets burnt a lot in the core of the earth. if you burn wood you get ash
When dry- good, yes. Great- no. Heat value is lower than oak, hickory, locust, ash. It is not often burned (except scrap) due to the value of the wood for woodworking. It is a very heavy wood.
wood
If it's solid ash wood, then it is pretty good and nice!
The amount of ash produced during combustion relative to the amount of fuel fed into the wood pellet stove. Ash content is one indicator of quality for wood pellet fuel. Ash content for wood pellets should be between one and three percent. 

type of wood used: from ash tree.
It is made from the wood of the ash tree.
Wood ash contain calcium carbonate, potassium compounds, phosphates, other metal oxides.
