Spike's Calculators

Sometimes all you know is the slope in a percentage (SP) and the horizontal length (HL) of the excavation. Knowing the vertical depth or height (VH) will enable you to estimate the amount of materials you get from the excavating with these measurements.

Formula: VH = HL * (SP ÷ 100)

slope percentage = 33.3%

14 * 12 + 1 = 169" 169 * (33.3 ÷ 100) 169 * 0.333 = 56 (rounded) = 4' 8"
