# Surface area of cube

The surface area of a cube is the total area of all its faces. Since a cube has six square faces that are all the same size, we can find the surface area by multiplying the area of one face by six.

The formula for the surface area of a cube is:

SA = 6s^2

where:

• SA is the surface area of the cube
• s is the length of one side of the cube

For example, let’s say we have a cube with a side length of 4 cm. We can find its surface area using the formula:

SA = 6s^2 = 6(4 cm)^2 = 6(16 cm^2) = 96 cm^2

So the surface area of the cube is 96 square centimeters.

## Surface area of cube step by step

Sure, here are the step-by-step instructions for finding the surface area of a cube:

1. Identify the length of one side of the cube. Let’s call this measurement s.
2. Use the formula for the area of a square to find the area of one face of the cube. Since all faces of a cube are squares, the area of each face is s^2.
3. Multiply the area of one face by 6, since a cube has 6 identical faces. This gives you the total surface area of the cube.
4. Write your final answer with the appropriate units squared. Since surface area is measured in square units, your answer will have units of length squared.

So, the complete step-by-step process for finding the surface area of a cube can be written as:

SA = 6s^2

where:

• SA is the surface area of the cube
• s is the length of one side of the cube
