Question

Need help in making this run correctly.

class Box:

def __init__(self,weight,length,width,height):

self.weight = weight

self.length = length

self.width = width

self.height = height

def getVolume(self,volume):

#volume = volume

volume = self.length * self.width * self.height

return volume

def getMassDensity(self,volume):

return self.weight/volume

def main():

box1 = Box(100,10,2,10)

print("For box # 1, the volume is %f and mass density is %f" %( box1.getVolume(), box1.getMassDensity() ) )

box2 = Box(200,50,5,40)

print("For box # 2, the volume is %f and mass density is %f" %( box2.getVolume(), box2.getMassDensity() ) )

the problume you have is in your getMassDensity routine you can't just use volume like that

so change it to

def getMassDensity(self):

return self.weight/self.getVolume()
