How to calculate concrete volume in a slab

Measure the length ($L$), width ($W$), and thickness ($T$) of the slab. Ensure all measurements are in the same units (e.g., meters or feet).

The formula for the volume of a rectangular slab is:

Where:

• $V$ is the volume of concrete
• $L$ is the length of the slab
• $W$ is the width of the slab
• $T$ is the thickness (or height) of the slab

Example: Calculate the volume of a slab that is 5 meters long, 3 meters wide, and 0.15 meters thick.

The volume of concrete required for the slab is $\text{2.25 m}^3$.
