in python

create a python class named Box that models a heavy "Box" with the following characteristics: 1. The class has four private instance variables L1, W1, H1 and W to store the length, Width, Height and Weight of the Box. Measurements are in meter and Kg. 2. This class has a constructors for four parameters that initializes the Box object's L.W.H.Weigh 3. This class has a method calculateVolume() which returns the volume (formula: L1-W1"H1) of the Box object 4. This class has a method calculateDensity() which returns the density of the Box (formula: weight/volume) check for divide by O. 5. creates an instance of the Box object with L1=10, W1=5, H1=5, W=100 and computes the Box's Volume and Density, then outputs the results to the user's screen.
