The weight of a standard brick can vary depending on its size, material, and moisture content. A typical red clay brick (commonly used in construction) weighs around 4.5 to 5 pounds (2 to 2.27 kg).
However, if you’re referring to a cube of brick, this would depend on the size of the cube. For example:
A 1-foot cube of brick, made up of smaller bricks, would weigh significantly more—approximately 1,440 pounds (about 650 kg), since a standard brick is around 4.5 to 5 pounds.
The weight can vary based on the type of brick, so it’s always best to check the specific product for a more accurate weight.
