<｜begin▁of▁sentence｜>### Instruction:
As a pharmaceutical sales representative, you're familiar with the importance of accurately assessing the dimensions of pharmaceutical products. Imagine you have two shipments of medication, each in unique boxes with known dimensions. Additionally, you receive a new shipment in a box with different dimensions. You need to compare the dimensions of the first two shipments' boxes to confirm if they are identical using the `__eq__` method, and then verify if the dimensions of the third shipment's box are different. This will help you ensure the accuracy of your inventory management.
### Response:
import igraph as ig

# Create two bounding box instances
bbox1 = ig.drawing.BoundingBox(100, 100)
bbox2 = ig.drawing.BoundingBox(100, 100)
bbox3 = ig.drawing.BoundingBox(150, 150)

# Check if two bounding boxes are equal
are_equal = bbox1 == bbox2  # Should return True
are_not_equal = bbox1 == bbox3  # Should return False

print('Bounding Box 1 and 2 are equal:', are_equal)
print('Bounding Box 1 and 3 are not equal:', are_not_equal)
