Cube Calculator

Cube calculator is used to calculate the volume of the cubic shape by using the length of the one side with any specific unit. It also finds the surface area of the cube and the diagonal of the cube by using the length of one side. 

What is a cube?

A Cube is a three-dimensional shape with six square or rectangular sides. It is a three-dimensional solid object bounded by six square faces, facets or sides, where three of its sides meet at the vertex.

  • Volume of Cube =
  • Surface Area of Cube = 6a²
  • Diagonal of Cube = Sqrt (3)*a


  • a = side


Find the volume, surface area, and diagonal of a cube with the given side 3.

Step 1: Fine the Volume

Volume= a³ = 3³ = 27.

Step 2: Find the surface area.

Surface Area = 6a² = 6 * 3² = 6 * 9 = 54.

Step 3: Find the diagonal.

Diagonal = Sqrt(3)*a = Sqrt(3) * 3 = 1.73 * 3 = 5.19
