River Rock Calculator

tons

River Rock Calculator comes in handy when trying to figure out how much river rock you will need for landscaping, construction, or any project involving decorative rocks.

Formula for River Rock Calculation

To find out the amount of river rock you will need, use the following formula:

Volume (cubic meters)=Length (m)×Width (m)×Depth (m)

Once you have the volume, now calculate the total weight using the material’s density:

Total Weight (kg)=Volume (cubic meters)×Density (kg/m³)

Example Calculation

Let’s say you are planning to cover a 12-meter long and 4-meter-wide garden area with river rock at a depth of 0.25 meters.

The density of river rock is approximately 1600 kg/m³.

So,

Volume = 12 m × 4 m × 0.25 m = 12 cubic meters

Total Weight = 12 cubic meters × 1600 kg/m³ = 19,200 kg

This means you will need 19,200 kg of river rock to cover the garden area.

Real-Life Applications

River rock is commonly used in landscaping projects, garden pathways, drainage systems, and decorative features.

Industries Using River Rock Calculations

  • Landscaping: For designing decorative garden beds, pathways, or ground covers.
  • Construction: Used for stabilising soil or as drainage layers.
  • Civil Engineering: Often applied in riverbanks and erosion control projects.

Ground Cover for Gardens0.2530-501600
Erosion Control0.3550-1001600

Tips for Accurate Calculation

  • Always account for extra material, as rocks may settle over time.
  • Check the density of the specific type of river rock you are using, as it can vary.
