Cube Formula
The cube formula helps us to find the volume of a cube. The cube of a number directly reflects the volume of a cube having an edge length equal to the given number. A cube is a 3D solid object with six square faces whose all the sides are of the same length. The volume of a cube is found by calculating the cube of the length of the side of the cube. Let us learn about the cube formula with a few solved examples in the end.
What Is the Cube Formula?
The cube is one of the five platonic solids and is also known as a regular hexahedron. Cube formula is expressed as, If the length of the cube is 's', then the volume of the cube will be:
s × s × s = s^{3}
Let us understand the cube formula better using a few solved examples.

Example 1: Find the volume of a Rubik's Cube of length 4 in.
Solution:
To find: The volume of a Rubik's cube.
The length of the side of the cube= 4 in. (given)
Using the cube formula,
volume = s × s × s = s^{3}
Put the values,
volume = 4 × 4 × 4 = 4^{3}
volume = 64
Answer: The volume of a Rubik's cube is 64 cubic inches.

Example 2: The dimensions of a cubic wardrobe are 64 in. Find its volume using the cube formula.
Solution:
To find: Volume of the wardrobe.
The dimensions of the wardrobe are: Length(l) = Width(w) = Height(h) = 64 in (given)
Using the cube formula,
volume = s × s × s = s^{3}
Put the values,
Volume = 64^{3}
Volume = 262144
Answer: The volume of the wardrobe is 262144 cubic inches.
