How to Calculate the Volume of a Cube - Formula and Examples
A cube is a congruent solid with six square faces, all with equal length dimensions. The volume of a cube is measured in cubic units. Think of the dice, or any other similar object, of any size. The volume refers to the amount of space occupied and if you know the dimensions of one side of the cube, you can easily calculate its volume. So wait no more and learn with this OneHowTo article how to calculate the volume of a cube with its formula and an example.
Using the formula for calculating the volume of a cube you can get a result simply and easily.
Measure the length of one of the sides or edges. It doesn't really matter which side you measure as all its dimensions are the same, it is a regular polyhedron with 6 equal sides. Normally, when making mathematical exercises, this information will be given to you so you can apply the formula to calculate the volume of a cube.
The formula for calculating the volume of a cube is equal to the length of its edge cubed: V=a³
Thus, you must multiply the dimensions of the side by itself 3 times.
Lets suppose that the edge of the cube is 6 cm, so we replace this value in the formula and make the relevant mathematical operation:
V = 63³ = 6x6x6 = 216 cm³
We have obtained the result by applying the formula for calculating the volume of a cube.
Always remember to be careful with the units of measurement you use in your calculations and the result, which must be expressed in cubic units. In this case, as the unit length has been measured centimetres, the resulting volume of the cube will be in cubic centimeters, and this should be indicated.
