Method #1 – Side from the volume
Calculator
Formula – How to calculate the side of the cube from the volume
Side = 3√Volume
Example
A cube has a volume of 1,000
Side = 3√1000 = 10
Method #2 – Side from the surface area
Calculator
Formula – How to calculate the side of a cube from the surface area
Side = √(Surface Area ÷ 6)
Example
A cube has a surface area of 600
Side = √(600 ÷ 6) = √100 = 10
Method #3 – Side from the perimeter
Calculator
Formula – How to calculate the side of the cube from the perimeter
Step 1 – Find the length of one side from the perimeter
Side = Perimeter ÷ 12
Example
A cube has a perimeter of 120
Side = 120 ÷ 12 = 10
Method #4 – Side from the interior diagonal
Calculator
Formula – How to calculate the side of the cube from the interior diagonal
Side = Diagonal ÷ √3
Example
A cube has an interior diagonal of 14
Side = 14 ÷ √3 = 14 ÷ 1.4422 = 9.7074
Method #5 – Side from the face diagonal
Calculator
Formula – How to calculate the side of a cube from the face diagonal
Side = √(Diagonal2 ÷ 2)
Example
A cube has a face diagonal of 14
Side = √(142 ÷ 2) = √(196 ÷ 2) = √98 = 9.89949
