# Trapazoid Volume Calculators

A shape known as a Trapezoid in North America or a Trapezium in the rest of the English speaking world, can come in many shapes, but has to have at least one pair of parallel running sides. To calculate the volume of this shape you need to enter the lengths of these two sides, the distance between these lengths and the depth of the slab.
