Boulder Weight Calculator

Formula

The formula for calculating the weight of a boulder is:

\[ W_{b} = L \times W \times H \times d \]

Where:

\( W_{b} \) is the boulder weight (lbs)
\( L \) is the boulder length (ft)
\( W \) is the boulder width (ft)
\( H \) is the boulder height (ft)
\( d \) is the density (lbs/ft³)

What is the weight of a boulder?

A boulder's weight is determined by its total volume and the density of the type of rock. Not all boulders have the same density. For example, sandstone rock has a density of 150 lbs/ft³, while limestone rock has a density of 175 lbs/ft³.

Example Calculation

Let's assume the following values for a sandstone boulder:

Length (L) = 3 ft
Width (W) = 2 ft
Height (H) = 1.5 ft
Density (d) = 150 lbs/ft³

Using the formula to calculate the boulder weight:

\[ W_{b} = 3 \times 2 \times 1.5 \times 150 = 1350 \text{ lbs} \]

The boulder weight is 1350 lbs.
