From helping stop floods to lining the tops of trenches during World War I, the humble sandbag is a cheap and effective solution to many problems.
So what is the weight of a sandbag?
On average, a sandbag will weigh around 40 pounds (18 kg).
The most common sandbag size is 14in x 26in. This makes them sturdy enough to do their job, while still being light enough for almost anyone to carry.
Bulk bags are larger than traditional sandbags and, when filled, can weigh as much as 2,200 pounds (1,000 kg).
It is thought sandbags were first used in the late 18th century.
One of the earliest noted usages of sandbags came during the American Revolutionary War in 1781.
Sandbags were used extensively during World War I to line the tops of trenches.

Their composition makes them effective at absorbing bullets and dissipating explosive blasts.
Today, sandbags are most commonly used as a deterrent against flood waters.
When sandbags are stacked high enough, they will prevent damaging flood waters from entering properties or other buildings.
For maximum effectiveness, sandbags should be placed parallel to the flow of the water.
