Example Calculation

Let’s understand how this tool works with a real-life gardening example.

Garden Bed Details:

• Length: 8 ft
• Width: 4 ft
• Depth: 1.5 ft
• Soil cost: $45 per cubic yard

Step-by-Step Calculation:

1. Soil Volume

Cubic feet = 8 × 4 × 1.5 = 48 cubic feet
Cubic yards = 48 ÷ 27 = 1.78 cubic yards

2. Soil Bags Needed

Each bag = 1.5 cubic feet
48 ÷ 1.5 = 32 bags (rounded up)

3. Total Cost

1.78 × 45 = $80.10

Final Result:

• Soil Required: 1.78 cubic yards
• Soil Bags: 32 bags
• Total Cost: $80.10

This helps gardeners clearly understand how much soil to buy before starting their project.
