Crystal River Rock Calculator

Formulas

For square or rectangular surfaces:

$$V = (A \times d) \times (1 + c)$$

For circular or elliptical surfaces:

$$V = (\pi \times \left(\frac{L}{2}\right)^2 \times D) \times (1 + c)$$

Where:

• $V$ is the volume needed;
• $A$ is the area;
• $d$ is the depth;
• $c$ is the wastage percentage.

To calculate the weight:

$$W = V \times \rho$$

Where:

• $W$ is the weight;
• $\rho$ is the density of the rock.
