# How to find the surface area of a cube?

Do you want to know **“How to find the surface area of a cube?”** Then this post is for you. A cube is a three-dimensional shape with six square faces. It is a regular hexahedron, which means all of its faces are the same size and shape. The cube is the only regular hexahedron.

## How to find the surface area of a cube?

There are a few different ways to find the surface area of a cube. You can use this formula A = 6s^2 or A=6a^{2} to find out the surface area of a cube. One way is to find the area of each of the six faces of the cube and then add them all together. Another way is to find the length of one of the edges of the cube and then multiply that by 24 (since there are 24 edges on a cube).

To find the area of each face of the cube, you can use the formula for the area of a square (which is just the length of one side squared). So, if the length of one side of the cube is s, the area of each face would be s^2. Therefore, the surface area of the cube would be 6s^2.

To find the length of one of the edges of the cube, you can use the formula for the diagonal of a square (which is just the length of one side squared plus the length of the other side squared and then take the square root of that). So, if the length of one side of the cube is s, the length of the edge would be sqrt(s^2 + s^2) = sqrt(2s^2). Therefore, the surface area of the cube would be 24sqrt(2s^2).

### Example: If the surface area of a cube equals 96, what is the length of one side of the cube?

If the surface area of a cube equals 96, the length of one side of the cube is 4. This is because the surface area of a cube is equal to 6 times the length of one side squared. Therefore, if we take the square root of 96 and divide it by 6, we get 4.

## What is the Surface Area of a Cube?

A cube is a three-dimensional object with six faces, all of which are square. The surface area of a cube is the sum of the areas of its six faces.

To find the surface area of a cube, you need to know the length of one of its sides. Let’s say the side length is s. The surface area of the cube is then 6s^2.

You can also think of the surface area of a cube as the area of a square that would just fit around the outside of the cube. The surface area of a cube is therefore the same as the area of a square with sides that are s * 2, or 2s.
