CUBE
- All the edges in the Cube has same length. OR We can say, Cube is nothing but 6 equal squares.
Surface Area of a Cube
- If we know the length of any edge in Cube then we can calculate the surface area of a Cube using the formula:
- Surface Area of a Cube = 6l² (Where l is the Length of any side of a Cube).
- Area of a square = l² Since the Cube is made of 6 equal squares, Surface Area of a Cube = 6l²
- If we already know the Surface Area of Cube and then we can calculate the length of any side by altering the above formula as:
l = √sa / 6 (sa = Surface Area of a Cube)click below button to copy the code. By Python tutorial team
Volume of a Cube
- The amount of space inside the Cube is called as Volume. If we know the length of any edge of a Cube then we can calculate the Volume of Cube using formula:
Volume = l * l * l
The Lateral Surface Area of a Cube = 4 * (l * l)click below button to copy the code. By Python tutorial team
Python Program to find Volume and Surface Area of a Cube
- This program allows user to enter any side of a Cube.
- Using this value, this Python program will calculate the Surface Area of a cube, Volume of a cube and Lateral Surface Area of a Cube as per the formulas.
Sample Code
# Python Program to find Volume and Surface Area of a Cube
l = float(input('Please Enter the Length of any Side of a Cube: '))
sa = 6 * (l * l)
Volume = l * l * l
LSA = 4 * (l * l)
print("\n Surface Area of Cube = %.2f" %sa)
print(" Volume of cube = %.2f" %Volume)
print(" Lateral Surface Area of Cube = %.2f" %LSA)click below button to copy the code. By Python tutorial team
Analysis
- Below statements will ask the user to enter the length value and it will assign the user input values to respected variable.
l = float(input('Please Enter the Length of any Side of a Cube: '))click below button to copy the code. By Python tutorial team
- Next, We are calculating Volume, Surface Area and Lateral Surface Area of a Cube using their respective Formulas:
sa = 6 * (l * l)
Volume = l * l * l
LSA = 4 * (l * l)click below button to copy the code. By Python tutorial team
- Following print statements will help us to print the Volume, Lateral Surface Area and Surface area of a Cube
print("\n Surface Area of Cube = %.2f" %sa)
print(" Volume of cube = %.2f" %Volume)
print(" Lateral Surface Area of Cube = %.2f" %LSA)click below button to copy the code. By Python tutorial team
Output
Learn Python - Python tutorial - Python Program to find Volume and Surface Area of a Cube - Python examples - Python programs
- We entered the Length of any side of a Cube = 5
The Surface Area of a Cube is
Surface Area of a cube = 6 * length * length
Surface Area of a cube = 6 * 5 * 5
Surface Area of a cube = 150
The Volume of a Cube is
Volume of a cube = length * length * length
Volume of a cube = 5 * 5 * 5
Volume of a cube = 125
The Lateral Surface Area of a Cube is
Lateral Surface Area of a cube = 4 * length * length
Lateral Surface Area of a cube = 4 * 5 * 5
Lateral Surface Area of a cube = 100
- In the above example we got Surface area = 150 when the length = 5. Let us do the reverse approach (Calculate the length of a Cube using Surface Area = 150)
Length of a cube = √sa / 6
Length of a cube = √150 / 6
Length of a cube = √25
Length of a cube = 5
Python Program to find Volume and Surface Area of a Cube using functions
- This program allows user to enter any side of a Cube.
- We will pass the value to the function argument and then it will calculate the Surface Area of a Cube, Lateral Surface Area of a Cube and Volume of a Cube as per the formula.
Sample Code
# Python Program to find Volume and Surface Area of a Cube Using Functions
def Vo_Sa_Cone(l):
sa = 6 * (l * l)
Volume = l * l * l
LSA = 4 * (l * l)
print("\n Surface Area of Cube = %.2f" %sa)
print(" Volume of cube = %.2f" %Volume)
print(" Lateral Surface Area of Cube = %.2f" %LSA)

Analysis
- First, We defined the function with one argument using def keyword.
- It means, User will enter the length of a cube.
- Next, We are calculating the Surface Area of a Cube, Lateral Surface Area of a Cube and Volume of a Cube as per the formula
NOTE: We can call the function with arguments in .py file directly or else we can call it from the python shell. Please don’t forget the function arguments
