Body Mass Index

• Problem Description

  
  Write a program that computes the body mass index (BMI) of an individual. 
  
  Your program should begin by reading a height and weight from the user. If you read the height in meters and the weight in kilograms then body mass index is computed using this slightly simpler formula:
  
  BMI = weight / height *height
  
  Use round function in the final output value

• CODING ARENA

• a=float(input())

  b=int(input())

  c=b/(a*a)

  print("The BMI IS",round(c,2))

• Test Case 1

  
  Input (stdin)

  1.69
  
  64
  
  

  Expected Output

  The BMI IS 22.41

• Test Case 2

  
  Input (stdin)

  1.72

  Expected Output

  The BMI IS 24.0

Area of a Room

• Problem Description

  
  Write a program that asks the user to enter the width and length of a room. 
  
  Once the values have been read, your program should compute and display the area of the room. 
  
  The length and the width will be entered as floating point numbers. Include units in your prompt and output message; either feet or meters, depending on which unit you are more comfortable working with.
  
  Formula = length*width

Three Idiots

• Problem Description

  
  Create a program that reads three integers from the user and displays them in sorted order (from smallest to largest). 
  
  Use the min and max functions to find the smallest and largest values. 
  
  The middle value can be found by computing the sum of all three values, and then subtracting the minimum value and the maximum value.

• CODING ARENA

• a=[]

  for i in range(3):

      b=int(input())

      a.append(b)

  a.sort()

  print("The minimum value is",a[0])

  print("The maximum value is",a[2])

  print("The middle value is",a[1])

• Test Case 1

  
  Input (stdin)

  25
  
  12
  
  1988
  
  

  Expected Output

  The minimum value is 12
  
  The maximum value is 1988
  
  The middle value is 25

• Test Case 2

  
  Input (stdin)

  9
  
  19
  
  1972
  
  

  Expected Output

  The minimum value is 9
  
  The maximum value is 1972
  
  The middle value is 19

Convert integer to float

• Problem Description

Gravity Fall

• Problem Description

  
  Create a program that determines how quickly an object is traveling when it hits the ground. The user will enter the height from which the object is dropped in meters (m).
  
  Because the object is dropped its initial speed is 0m/s. Assume that the acceleration due to gravity is 9.8m/s. 
  
  vf =squareroot(vi+2ad) 
  
  You can use the formula given above to compute the final speed, vf , when the initial speed, vi , acceleration, a, and distance, d, are known

• CODING ARENA

• import math

  a=int(input())

eLab Petrol Bunk

• Problem Description

  
  In the United States, fuel efficiency for vehicles is normally expressed in miles-pergallon (MPG).
  
  In Canada, fuel efficiency is normally expressed in liters-per-hundred kilometers (L/100 km). 
  
  Use your research skills to determine how to convert from MPG to L/100 km. 
  
  Then create a program that reads a value from the user in American units and displays the equivalent fuel efficiency in Canadian units.
  
  Note:
  
  Formula is --> 282.48 / fuel efficiency in MPG.
