A prism has the same cross section all along its length. The diagram further down this page shows an example of an irregular prism which has then be split into sections. Each cross section of the irregular prism has exactly the same dimensions and area.
An irregular shape is a shape which does not conform to standard defined and repeatable mathematical rules.
The Volume of an Irregular Prism is calculated using the following equation:
Note: Remember to use the same measurement unit for each dimension when calculating the volume of an object.
The volume of solid objects like irregular prisms are measured in:
The volume of liquids are measured in:
The online Irregular Prism calculator below will automatically calculate the volume of the Irregular Prism based on the measurements you enter.
You will also have a running total which builds as you enter new dimensions into the volume calculator.
