feet.**Enter Riprap Width (ft):**Input the width in feet. For instance, enter`5`

feet.**Enter Riprap Depth (in):**Input the depth in inches. For example, enter`12`

inches.**Click Calculate:**The calculator will show the weight in pounds.

### Formula

The formula to calculate riprap weight is:

`$\text{Weight(lbs)}=\frac{\text{Length(ft)}\times \text{Width(ft)}\times \text{Depth(in)}}{12}\times 156.07$`

**Variables**

Variable | Description |
---|---|

`Length (ft)` |
Length in feet |

`Width (ft)` |
Width in feet |

`Depth (in)` |
Depth in inches |

`Weight (lbs)` |
Weight in pounds |

### 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
