What is a Cube?

Cube Volume Calculator

A cube is a three-dimensional solid object bounded by:

  • Six square faces
  • Six facets or sides with three meeting at each vertex.

The Volume of a Cube is calculated using the following equation:

  • Width x Length x Height
  • As the Width, Length and Height are all the same measurement for a cube, we simplyfy this to a3 [with a being the length of one of the edges]

Note: Remember to use the same measurement unit for each dimension when calculating the volume of an object.

The volume of solid objects are measured in:

  • cubic feet
  • cubic meters
  • cubic yards

The volume of liquids are measured in:

  • litres
  • quarts
  • pints
  • gallons

The online cube calculator below will automatically calculate the volume of the cube based on the measurement you enter.

You will also have a running total which builds as you enter new dimensions into the volume calculator.

Mathematics Volume Calculators

  • 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
