When working with aggregates like gravel, sand, or crushed stone, it's important to know how much area they will cover. So here is a simple and easy tool, the Aggregate Coverage Calculator helps you determine the coverage area based on the volume of aggregate and the desired depth.

Formula for Aggregate Coverage Calculation

The coverage area is calculated using the simple formula:

$\text{Coverage Area} = \frac{\text{Volume of Aggregate}}{\text{Depth of Layer}}$

In Mathematical Form

$A = \frac{V}{D}$

Where:

• A = Coverage Area (square meters or square feet)
• V = Volume of aggregate (cubic meters or cubic feet)
• D = Depth of aggregate layer (meters or inches)

Step-by-Step Calculation Process

Convert Volume to Cubic Meters

If the volume is given in cubic feet, convert it to cubic meters using:

$V_{m^3} = V_{ft^3} \times 0.0283168$

Convert Depth to Meters

If the depth is in inches, convert it to meters:

$D_m = D_{in} \times 0.0254$

If the depth is in centimeters, convert it to meters:

$D_m = \frac{D_{cm}}{100}$

Calculate Coverage Area

Now, apply the coverage formula:

$A_{m^2} = \frac{V_{m^3}}{D_m}$

Convert to Square Feet (if needed)

If you need the coverage area in square feet, use the conversion:

$A_{ft^2} = A_{m^2} \times 10.7639$

Example Calculation

Problem:

You have 20 cubic feet of gravel, and you want to spread it at a depth of 3 inches. How much area will it cover?

Solution:

Step 1: Convert Volume to Cubic Meters

$V_{m^3} = 20 \times 0.0283168 = 0.56634 \text{ m}^3$

Step 2: Convert Depth to Meters

$D_m = 3 \times 0.0254 = 0.0762 \text{ m}$

Step 3: Calculate Coverage Area in Square Meters

$A_{m^2} = \frac{0.56634}{0.0762} = 7.43 \text{ m}^2$

Step 4: Convert to Square Feet

$A_{ft^2} = 7.43 \times 10.7639 = 79.96 \text{ ft}^2$

Final Answer:

The gravel will cover 7.43 square meters or 79.96 square feet.

Conclusion

Using the Aggregate Coverage Calculator, you can quickly estimate how much area your material will cover. By converting units correctly and applying the formula, you can ensure efficient material use for landscaping, construction, or any other project.
