>Hello Sohib EditorOnline! If you are looking for a guide on how to calculate the surface area of a cube (kubus), you have come to the right place. In this article, we will break down the steps on how to do this calculation in a clear and simple way. Let’s get started!

What is a Cube?

A cube is a three-dimensional shape that has six square faces of equal size. It is a regular solid and has equal edges and angles. This makes calculating its surface area quite easy. To find the surface area of a cube, you need to know the length of one of its edges. Let’s dive into the calculation method.

Step 1: Measure the Edge Length of the Cube

The first thing you need to do is to measure the length of one of the edges of the cube. You can use a ruler or any other measuring tool. Let’s say the length of the edge is 5 cm.

Step 2: Identify the Number of Faces of the Cube

A cube has six faces, and each face is a square. To calculate the total surface area of the cube, you need to find out the area of each square face. The formula to calculate the area of a square is:

Area of Square = Length of One Side x Length of One Side

Step 3: Calculate the Area of One Face

Now that you know the formula to calculate the area of a square, you can easily find the area of one face of the cube. Since all the faces of a cube are of equal size, you can use the same formula to calculate the area of each face. So, if the length of one edge is 5 cm:

Area of One Face = 5 cm x 5 cm = 25 cm²

Step 4: Multiply the Area of One Face by the Number of Faces

As mentioned earlier, a cube has six square faces. To calculate the total surface area of the cube, you need to multiply the area of one face by the number of faces. So:
