To calculate the total cost:
\[ \text{Total Cost} = \text{Volume} \times \text{Price} \]
Where:
The volume of mulch or wood required is calculated based on the shape of the area (square/rectangle), the dimensions, and the depth (converted from inches to feet). The total cost is then determined by multiplying the volume by the price per unit volume.
Let's assume the following values for a rectangular area:
Using the formula:
\[ \text{Volume} = 10 \times 5 \times \left(\frac{24}{12}\right) = 100 \text{ cubic feet} \]
Converting to cubic meters:
\[ \text{Volume} = 100 \times 0.0283168 = 2.83168 \text{ cubic meters} \]
Calculating the total cost:
\[ \text{Total Cost} = 2.83168 \times 30 = 84.95 \]
The total cost is $84.95.
