Activity

1- Consider the following program:

rect=Rectangle2D(4,5)

print (rect, "area="+str(rect. area( ) ) )

-with the corresponding output:

w=4, h=5 area=20

Write the class Rectangle2D using the public attributes w, h (for width and height).

2- Consider the following program:

box=Box3D (4 ,5,2)

print (box, "volume="+str(box. volume ( ) ) )

-with the corresponding output:

w=4, h=5, d=2 volume=40

Write the class Box3D that inherits from Rectangle2D and uses the additional public attribute d (for depth). Every methods should use the super operator (including the constructor_init_).

3- Consider the following program:

box1=Box 3D ( 2 , 2, 1)

box2=Box 3D ( 2 , 1, 2)

box3=Box 3D ( 3, 4, 3)

print (box1+box2)

print (box3-box2)

print (box]*box2*box3)

print ( (boxl*box2) /2)

with the corresponding output:

w=4, h=3, d=3

w=1, h=3, d=1

w=12, h=8, d=6

w=2.0, h=1.0, d=1.0

Write the new methods you would have to implement in the class Box3D to enable such operator overloading results as shown above.

4- Consider the following program:

box=Box 3D ( 3, 2, 1)

faces=box. extract_faces ( )

for rect in faces:

print (rect)

-with the corresponding output:

w=3. h=2

w=3,h=1

w=2. h=1

Write the method extract_faces ( ). Use instances of the Rectangle2D class.
