Spike's Calculators

Estimate the amount of material from a rectangle-shaped excavation.

As the material is excavated it will increase in volume (bank to loose state). The amount of volume increase depends on the swell or bulking factor of the excavated material.

*This calculator uses a preset swell factor percentage for a material consisting of an earth and rock mixture. If you know the swell factor of the material you are excavating you can change the swell factor percentage accordingly.*

The formula used: excavated material = L *W * D ÷ 27 *(SF ÷100)

The material excavated consists of "Hard Pan" with a swell factor of 25%

34 * 22 * 6 = 4488 cubic feet

4488 ÷ 27 = 166.2 cubic yards

166.2 * (25 ÷ 100) =

166.2 * (0.25) = 41.6 cubic yards of volume increase

166.2 + 41.6 = 207.8 cubic yards of total volume of excavated material
