a=int(input("Enter the side of the cube"))

b=6*a*a

print ("surface area of the cube",b)

Explanation,

the first line is for input

which means it will ask for the measurements

then second is the formula

and third is that it will print the calculated value

find Volume and Surface Area of a Cube

In this article we will show you, How to write Python Program to find Volume and Surface Area of a Cube with example. Before we step into the program, Let see the definitions and formulas behind Surface area of a Cube and Volume of a Cube

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)

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)

Python Program to find Volume and Surface Area of a Cube

This python 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.

PYTHON 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)

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: '))

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)

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)

OUTPUT

Python Program to find Volume and Surface Area of a Cube

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.

PYTHON 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)

Vo_Sa_Cone(6)

OUTPUT

Python Program to find Volume and Surface Area of a Cube using functions

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
