Cuboid
- Cuboid is a 3D object made up of 6 Rectangles. All the opposite faces (i.e Top and Bottom) are equal.
Surface Area of a Cuboid
- The Total Surface Area of a Cuboid is the sum of all the 6 rectangles areas present in the Cuboid.
- If we know the length, width and height of the Cuboid then we can calculate the Total Surface Area using the formula:
Area of Top & Bottom Surfaces = lw + lw = 2lw
Area of Front & Back Surfaces = lh + lh = 2lh
Area of both sides = wh + wh = 2whclick below button to copy the code. By Python tutorial team
- The Total Surface Area of a Cuboid is the sum of all the 6 faces. So, we have to add all these area to calculate the final Surface Area
Total Surface Area of a Cuboid = 2lw + 2lh + 2wh
It is equal: Total Surface Area = 2 (lw + lh +wh)click below button to copy the code. By Python tutorial team
Volume of a Cuboid
- The amount of space inside the Cuboid is called as Volume.
- If we know the length, width and height of the Cuboid then we can calculate the Volume using the formula:
Volume of a Cuboid = Length * Breadth * Height
Volume of a Cuboid = lbh
The Lateral Surface Area of a Cuboid = 2h (l + w)click below button to copy the code. By Python tutorial team
Python Program to find Volume and Surface Area of Cuboid
- This Python program allows user to enter the length, width and height of a Cuboid.
- Using these values, compiler will calculate the Surface Area of a Cuboid, Volume of a Cuboid and Lateral Surface Area of a Cuboid as per the formulas.
Sample Code
# Python Program to find Volume and Surface Area of Cuboid
length = float(input('Please Enter the Length of a Cuboid: '))
width = float(input('Please Enter the Width of a Cuboid: '))
height = float(input('Please Enter the Height of a Cuboid: '))
# Calculate the Surface Area
SA = 2 * (length * width + length * height + width * height)
# Calculate the Volume
Volume = length * width * height
# Calculate the Lateral Surface Area
LSA = 2 * height * (length + width)
print("\n The Surface Area of a Cuboid = %.2f " %SA)
print(" The Volume of a Cuboid = %.2f" %Volume);
print(" The Lateral Surface Area of a Cuboid = %.2f " %LSA)click below button to copy the code. By Python tutorial team
Analysis
- Below statements will ask the user to enter length, width and height values and it will assign the user input values to respected variables.
- Such as first value will be assigned to length, second value to width and third value will be assigned to height
length = float(input('Please Enter the Length of a Cuboid: '))
width = float(input('Please Enter the Width of a Cuboid: '))
height = float(input('Please Enter the Height of a Cuboid: '))click below button to copy the code. By Python tutorial team
- Next, We are calculating Volume, Surface Area and Lateral Surface Area of a Cuboid using their respective Formulas:
# Calculate the Surface Area
SA = 2 * (length * width + length * height + width * height)
# Calculate the Volume
Volume = length * width * height
# Calculate the Lateral Surface Area
LSA = 2 * height * (length + width)click below button to copy the code. By Python tutorial team
- Following print statements will help us to print the Volume and Surface area of a Cuboid
print("\n The Surface Area of a Cuboid = %.2f " %SA)
print(" The Volume of a Cuboid = %.2f" %Volume);
print(" The Lateral Surface Area of a Cuboid = %.2f " %LSA)click below button to copy the code. By Python tutorial team

Analysis
- In the above Example, We inserted Values Length = 8, Width = 5 and Height = 6
The Volume of a Cuboid for the Given Measures are:
Volume of a Cuboid = lbh = l * w * h
Volume of a Cuboid = length * width * height
Volume of a Cuboid = 8 * 5 * 6
Volume of a Cuboid = 240
The Volume of a Cuboid is 240
The Total Surface Area of a Cuboid for the Given Measures are:
Total Surface Area of a Cuboid = 2lw + 2lh + 2wh
Total Surface Area of a Cuboid = 2 (lw + lh +wh)
Total Surface Area of a Cuboid = 2*(length * width + length * height + width * height)
Total Surface Area of a Cuboid = 2 * ( (8 * 5) + (8 * 6) + (5 * 6) )
Total Surface Area of a Cuboid = 2 * (40 + 48 + 30)
Total Surface Area of a Cuboid = 2 * 118
Total Surface Area of a Cuboid = 236
The Total Surface Area of a Cuboid is 236
Python Program to find Volume and Surface Area of Cuboid using functions
- This program allows user to enter the length, width and height values.
- We will pass those values to the function argument and then it will calculate the Surface Area and Volume of a Cuboid as per the formula.
Sample Code
# Python Program to find Volume and Surface Area of a Cuboid using Functions
def Vo_Sa_Cuboid(length, width, height):
# Calculate the Surface Area
SA = 2 * (length * width + length * height + width * height)
# Calculate the Volume
Volume = length * width * height
# Calculate the Lateral Surface Area
LSA = 2 * height * (length + width)
print("\n The Surface Area of a Cuboid = %.2f " %SA)
print(" The Volume of a Cuboid = %.2f" %Volume)
print(" The Lateral Surface Area of a Cuboid = %.2f " %LSA)
