How to Calculate Epoxy for a River Table
Calculating the volume of epoxy needed for a river table is essential to avoid wasting expensive materials. The calculation depends on the shape of your project.
For Rectangular Tables
This is a simple volume calculation. The formula is: Length x Width x Depth. This gives you the volume in cubic inches. To convert that to U.S. Gallons, you divide the result by 231.
For Circular Tables
To find the volume of a cylinder, the formula is: π x Radius² x Depth. Remember, the radius is half of the diameter. Once you have the volume in cubic inches, divide by 231 to get U.S. Gallons.
