Cube Surface Area Calculator
Calculate the surface area of a cube. Enter your values, review the formula, and use the worked result as a quick check for everyday planning.
Cube Surface Area Calculator
Calculate the surface area of a cube.
e.g., cm, m, ft, in
Results
Surface Area
96 sq units
Formula: Surface Area = 6 * side²
Cube Surface Area from Side Length
Calculate the total surface area of a cube. Since all six faces are identical squares, the surface area is simply six times the area of one face.
Formula
Surface Area = 6 × side². Each face has area side². A cube has 6 identical faces.
Worked example
Side 4: surface area = 6 × 16 = 96 sq units. A cubic gift box with 10 cm sides has 6 × 100 = 600 cm² of wrapping paper needed (ignoring overlap).
Practical guidance
Painting and wrapping estimates
Surface area tells you how much paint, wrapping paper, or laminate is needed to cover all exterior faces. A 1 m cube needs 6 m² of material. For objects that are not cubes, use the rectangular prism surface area calculator.
Heat transfer and insulation
Surface area relates to heat loss/gain in buildings and equipment. A cube-shaped container with 2 m sides has 24 m² of surface area through which heat can transfer.
