# Trapezium Slab Concrete Calculator

Calculate the amount of concrete needed to pour a slab in the shape of a Trapezium (Trapezoid). A Trapezium is a shape with at least one pair of parallel sides.

### Trapazoid Volume Calculator

#### Calculation

- enter the length of the first parallel running side measured in metres
- the length of the second parallel running side in me in metres
- the distance between the two parallel running sides in metres

#### Results

- the volume of concrete needed in cubic metres
- amount of concrete converted to cubic yards

### When Ordering Concrete

This concrete calculator will help you in estimating the amount of concrete needed for your project. The amount given as needed, does not include any waste. It is recommended, depending on the job you are doing, to add anywhere from an extra 4% to 10% to your concrete order to make sure you have enough concrete to finish the job.
