What is a cube?
A cube is a three-dimensional solid object bounded by six square faces with three meeting at each vertex. It has 8 vertices, 12 edges, and 6 faces. It is a trigonal trapezohedron in four orientations and regular square prism in three orientations.
Cube formulas
Volume of cube
Cube volume formula can be written as:
V = a³
Surface area of cube
Surface area of cube formula can be expressed as:
S = 6 × a²
Diagonal of cube
The formula for diagonal of cube can be stated as:
D = √3×a
Where,
a is length of side,
V is volume,
S is surface area, and
D is diagonal of cube.
Our cube volume calculator uses all of the above formulas to find these cube parameters.
How to calculate volume of cube?
Example: If length of side of cube is 8 cm, find the volume of cube.
Cube calc: find V
Step 1: Identify the given values.
a = 8 cm
Step 2: Place the value in volume of cube equation.
V = a³
V = 8³ = 8 × 8 × 8
V = 512 cm3
How to calculate surface area of cube?
Example: If length of side of cube is 3.5 cm, find the surface area of cube.
Cube calc: find S
Step 1: Identify the given values.
a = 3.5 cm
Step 2: Place the value in surface area of cube equation.
S = 6 × a²
S = 6 × 3.5²
S = 73.5 cm2
How to find diagonal of cube?
Example: If length of side of cube is 10 cm, find the diagonal length of cube.
Cube calc: find d
Step 1: Identify the given values.
a = 10 cm
Step 2: Place the value in surface area of cube equation.
D = √3×a
D = √3×10
D = 17.32 cm
