It is a 3-dimensional symmetrical shape. It is a solid bounded by 6 square faces with 3 sides meeting at each vertex.
A cube has 6 faces, 12 edges and 8 vertices. It is also known as a Hexahedron.
We know that ‘Volume’ in maths is the amount of space covered by a certain 3D object and is measured in cubic units.
The volume of a cube is the total space in cubic units occupied by 6 sides of the cube, in a 3D space.
Hence, the volume of a cube is equal to the product of its length, width and height.
Unlike 2D shapes, 3D shapes have an additional dimension apart from length and width, called Height or Thickness.
As mentioned in the definition, the cube is a symmetrical shape, i.e., each side of it is of the same size. For example, l = w = h = the same length say, s
There are 2 ways to find the volume of cube:
– By finding the edge length– By finding the diagonal.
Method 1
Method 2
Use any of the methods depending on the given data to find the Volume of a Cube.
Suppose the length of the diagonal of a cube is given as 3 inches.
