The Sand Required for a Sandbag Wall calculator estimates volume of sand needed for  a single bag wide wall of height (H) and length (L).

INSTRUCTIONS: Choose units and enter the following:

• (L)  This is the length of the sandbag wall.
• (H)  This is the height of the sandbag wall.

Volume of Sand (V): The calculator returns the volume of sand in cubic yards.  However, this can be automatically converted to compatible units via the pull-down menu.

### The Math / Science

The volume of sand needed for a sandbag wall is approximately the walls length times its height times its width.   This equation assumes the width is one bag laid lengthwise.  The width of a standard bag is fourteen inches (14").  When partially filled with sand, the width is approximately twelve inches (12") which is  used in this formula.
