## Calculation Examples

### Example 1

**Riprap Length (ft):**15**Riprap Width (ft):**8**Riprap Depth (in):**10

**Calculation:**

**1. Multiply Length, Width, and Depth:**

$15\times 8\times 10=1200$

**2. Convert Depth to Feet:**

$\frac{1200}{12}=100$

**3. Multiply by Density:**

$100\times 156.07=15607$

**Result:** 15607 pounds

### Example 2

**Riprap Length (ft):**20**Riprap Width (ft):**5**Riprap Depth (in):**15

**Calculation:**

**1. Multiply Length, Width, and Depth:**

$20\times 5\times 15=1500$

**2. Convert Depth to Feet:**

$\frac{1500}{12}=125$

**3. Multiply by Density:**

$125\times 156.07=19508.75$

**4. Result:** 19508.75 pounds
