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:

- Base x Height

**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:

- cubic feet
- cubic meters
- cubic yards

The volume of liquids are measured in:

- litres
- quarts
- pints
- gallons

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.

**Cube Volume Calculator**- a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.**Cone Volume Calculator**- a cone is an three-dimensional geometric shape that tapers smoothly from a base (usually flat and circular) to a point called the apex or vertex.**Cylinder Volume Calculator**a cylinder is a three-dimensional solid object that has 2 parallel bases that are congruent circles of same diameter.**Rectangular Prism Volume Calculator**- a rectangle is any quadrilateral with four right angles. A prism has the same cross section all along its length**Irregular Prism Volume Calculator**- A prism has the same cross section all along its length. An irregular shape is a shape which does not conform to standard defined and repeatable mathematical rules**Pyramid Volume Calculator**- a pyramid is a [three-dimensional solid object] polyhedron formed by connecting a polygonal base and to a point, called the apex.**Sphere Volume Calculator**- a sphere is a perfectly round geometrical three-dimensional solid object.**Ellipsoid Volume Calculator**- An ellipsoid is a three-dimensional solid object with closed quadric surface that is a three dimensional analogue of an ellipse
