### Formula for Tree Weight Calculation

To estimate the weight of a tree, we use the following formula:

$$[

\text{Tree Weight} = \text{Tree Volume} \times \text{Wood Density}

]$$

#### Breaking Down the Formula:

**Tree Volume (cubic meters)**: Approximated using the cylinder volume formula:

$$[

\text{Volume} = \pi \times \left(\frac{\text{Diameter}}{2}\right)^2 \times \text{Height}

]$$

**Diameter**is the tree’s diameter at breast height (DBH) in meters (converted from centimeters).**Height**is the tree’s height in meters.**(\pi)**is a constant (approx. 3.14159).

**Wood Density (kg/mÂ³)**: This is the density of the tree’s wood type, a standard value in kilograms per cubic meter (kg/mÂ³). Different tree species have unique wood densities (e.g., oak is denser than pine).

### Step-by-Step Calculation Example

Let’s calculate the approximate weight of an oak tree with the following details:

**Height**: 10 meters**Diameter**: 30 centimeters**Wood Density**: 750 kg/mÂ³ (an average density for oak)

#### Step 1: Convert Diameter to Meters

Since the diameter is given in centimeters, we convert it to meters:

$$[

\text{Diameter in meters} = 30 \, \text{cm} \div 100 = 0.3 \, \text{m}

]$$

#### Step 2: Calculate the Tree Volume

Now we use the volume formula:

$$[

\text{Volume} = \pi \times \left(\frac{\text{Diameter}}{2}\right)^2 \times \text{Height}

]$$

Substitute the values:

$$[

\text{Volume} = 3.14159 \times \left(\frac{0.3}{2}\right)^2 \times 10

]$$

Breaking this down:

- $$(\frac{0.3}{2} = 0.15)$$
- $$((0.15)^2 = 0.0225)$$
- $$(3.14159 \times 0.0225 = 0.07069)$$
- $$(0.07069 \times 10 = 0.7069)$$ cubic meters

So, the **tree volume** is approximately **0.7069 mÂ³**.

#### Step 3: Calculate the Tree Weight

Finally, we calculate the weight by multiplying the volume by the wood density:

$$[

\text{Weight} = \text{Volume} \times \text{Density}

]$$

$$[

\text{Weight} = 0.7069 \times 750 = 530.18 \, \text{kg}

]$$

### Result:

The estimated weight of this oak tree is **approximately 530.18 kg**.

### Summary of Calculation Steps

**Convert diameter**to meters if needed.**Calculate volume**using tree height and diameter.**Multiply volume by wood density**to get the tree’s weight.

This formula provides an approximate weight, as actual weight can vary with tree structure and moisture content.
