Introduction
A cube is a 3-dimensional figure with 6 square faces. The surface area of a cube is the total area of all of its faces. To find the surface area of a cube, you need to find the area of each of its faces and then add them all together.
The area of a square is found by multiplying the length of the side by the width of the side. So, the area of a cube’s face is found by multiplying the length of the side by the width of the side.
The surface area of a cube is therefore found by multiplying the length of the side by the width of the side by the height of the side
Formulae
A cube is a three-dimensional figure with six square faces. The surface area of a cube can be calculated by multiplying the length of one side by the square of that length.
The surface area of a cube can be calculated using the following formula:
SA = 6 x (side length)²
For example, if the side length of a cube is 3 cm, the surface area of the cube will be:
SA = 6 x (3 cm)²
SA = 54 cm²
