What Is The Formula For Surface Area Of A Cube

The surface area formula for a cube is 6 x side 2 as seen in the figure below.

Given side of the cube a 5 cm surface area of a cube 6a 2 6 x 52 cm 2 6 x 25 cm 2 150 cm 2. This calculation requires only one measurement due to the symetricity of the cube. It is represented by 6a 2 where a is the side length of cube it is basically the total surface area. Surface area 6 a 2 surface area 6 3 2 surface area 6 3 3 surface area 6 9 surface area 54 cm 2 example 2.

Surface area of cube is the sum of areas of all the faces of cube that covers it. The area of one of the six faces of the cube is the area of a square with side a units. To find the surface area of a cube use the formula. Surface area of a cube.

Find the surface area if the length of one side is 5 cm. If you don t know the length of the sides you can find the surface area using volume. Just find the cube root of the volume which is equal to the length of one side of the cube. Formula of surface area of cube let us consider a cube whose each edge or side has length of a units.

Since a cube has six faces all you have to do is calculate the area of one face and multiply by 6 to find the total surface area. The surface area of a cube 6a 2 where a is the length of the side of each edge of the cube put another way since all sides of a cube are equal a is just the lenght of one side of a cube we have 96 6a 2 a 2 16 so that s the area of one face of the cube. The mathematical formula that results from this discussion is. What is the surface area of a cube of side 5 cm.

Surface area 6 a 2. The formula for surface area is equal to six times of square of length of the sides of cube. For a cube with sides of length l the surface area a 6l 2 a 6l2 area of a square. A few examples showing how to find the surface area of a cube example 1.

Side 2 is the surface of one of the sides and since the cube has 6 equal sides multiplying by 6 gives us the total cube surface area.
