# Calculate The Surface Area of A Cube

Last updated: Saturday, April 29, 2023

The surface area of a cube is the sum of the areas of all its faces. Since a cube has six faces that are all congruent squares, its surface area can be calculated as:

Surface area = 6 x (side length)^2

The surface area of a cube is a useful measurement in many applications, such as in packaging and shipping, where the amount of material needed to cover the cube's surface determines the cost. It is also important in architecture and engineering, where the surface area of a building or structure can affect the amount of materials needed for construction or maintenance.

The formula for determining the surface area of a cube is defined as:
$$SA$$ $$=$$ $$6$$ $$\cdot$$ $$a^2$$
$$SA$$: the surface area of the cube
$$a$$: the length of any side
The SI unit of surface area is: $$square \text{ } meter\text{ }(m^2)$$
