Surface Area of a Cube
Surface Area of a Cube
\[A = 6a^2\]
Variables
A = surface area (m²)
a = edge length of the cube (m)
Description
What is this formula?
This formula calculates the total surface area of a cube. A cube has six identical square faces, so the total area is six times the area of one face.
When to use it
Use this formula when determining the external surface area of cubic objects or structures.
Example
If a cube has an edge length of 3 m:
A = 6 × 3^2 = 54 m²
