## Flagstone Weight Formula

The following formula is used to calculate the Flagstone Weight.

FLW = FL * FW * FT * 165

Variables:

- FLW is the Flagstone Weight (lb)
- FL is the flagstone length (ft)
- FW is the flagstone width (ft)
- FT is the flagstone thickness (ft)

To calculate the flagstone weight, multiply the flagstone length, width, and thickness, then multiply by 165, or the density.

## How to Calculate Flagstone Weight?

The following steps outline how to calculate the Flagstone Weight.

- First, determine the flagstone length (ft).
- Next, determine the flagstone width (ft).
- Next, determine the flagstone thickness (ft).
- Next, gather the formula from above = FLW = FL * FW * FT * 165.
- Finally, calculate the Flagstone Weight.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

flagstone length (ft) = 10

flagstone width (ft) = 14

flagstone thickness (ft) = 2FLW = FL * FW * FT * 165 =** ** ?
