Surface Area of Cube

In the previous post we have discussed about Volume of Cube and In today's session we are going to discuss about Surface Area of Cube. A solid object that has six equal square faces is said to be cube, its structure is just like a regular hexahedron. Let's see how to find the Surface Area of Cube formula? To find the surface area of a cube we need to follow some of the steps which are mention below:

Step 1: To find the Surface Area of Cube first it is necessary to have the length of one side of a cube. According to the definition of a cube all the sides of a cube are same, so the length of all the sides is also same. Suppose we have length of one side of a cube is 21 inch. Then find the surface area of a cube. The formula to find the surface area of a cube is given by:

surface area of a cube = 6a2, here 'a' denotes the side of a cube.

Step 2: if we put the value of the edges of a cube in the formula then we get the surface area of a cube. So on putting the value in the given formula.

surface area of a cube = 6a2, here the value of 'a' is 21 inch.

surface area of a cube = 6 (21)2,

surface area of a cube = 6 * 441, so the surface area of a cube is 2646 inch2.

Now we will discuss some parts of a cube. (know more about Cube, here)

Face – All the sides of a cube are said to be the faces of a cube because cube is has all the sides of equal length. A cube having six faces and all faces are square. All the faces of a cube have four equal sides and four equal interior angles.

Edge – A line segment that is obtained when two edges are meeting at a same point. 12 edges are present in a cube, as we know that cube has all the faces are congruent to each other and all the edges has same length.

Stoichiometry Problems is deals with the chemistry, it shows the quantitative relationship in between reactant and products. To prepare for the board exam please go through cbse latest sample papers.
