Cube Calculator

A cube is a three-dimensional geometric shape with six identical square faces. It is one of the five Platonic solids, regular polyhedra with congruent faces. Cubes are commonly used in mathematics, physics, and engineering due to their simple structure and well-defined properties.

Formulae

Several formulae can be used to calculate the volume, surface area, and diagonal length of a cube.

• Volume: The volume of a cube is calculated using the following formula:

V = a³

where:

• V is the volume of the cube
• a is the length of one of the side edges of the cube

For example, the volume of a cube with a side edge length of 5 inches is:

V = 5 inches³ = 125 cubic inches

• Surface area: The surface area of a cube is calculated using the following formula:

A = 6a²

where:

• A is the surface area of the cube
• a is the length of one of the side edges of the cube

For example, the surface area of a cube with a side edge length of 5 inches is:

A = 6 × 5 inches² = 150 square inches

• Diagonal length: The diagonal length of a cube is calculated using the following formula:

d = a√3

where:

• d is the diagonal length of the cube
• a is the length of one of the side edges of the cube

For example, the diagonal length of a cube with a side edge length of 5 inches is:

d = 5 inches√3 = 8.66 inches
