A cube is a three dimensional geometrical containing six sides. Square area of the cube is the measure of how much area a cube needs to cover itself.
If a2 is the area of the each side of the cube and there are six sides in the cube. Hence the surface area (SA) of the cube is given by

Surface Area of a Cube Calculator is a online tool which calculates the surface area of the cube if the side value a is entered in the block provided. It is expressed in square units.  
To solve the surface area of the cube you need to follow the following steps.
Step 1 : Read the given problem and note down the given side a.

Step 2 : The surface area formula is given by A = 6a2. Substitute the value and get the answer.
Below are given some problems based on surface area of the cube which may be helpful for you.

Solved Examples

Question 1: Find the surface area of the cube if the side is 3 cm.
Solution:
 
Step 1: Given side of the cube a = 3cm.

Step 2: The surface area of the cube is given by
SA = 6 $\times$ a2
     = 6 $\times$ 32
     = 54 cm2.
 

Question 2: Find the surface area for a cube of length 5 units.
Solution:
 
Step 1 : Given side of the cube a = 5 units,

Step 2 : The surface area of the cube is given by
SA = 6 $\times$ a2
     = 6 $\times$ 52
     = 150 square units.
