He Problem About Volume STORY beam

1. A bath in it is the size of 80 cm x 60 cm x 40 cm, if the tub is filled with an average speed of 4 liters / minute, then do take to the tub memenuhkan
Answer
From the above problem we have is that the form of a bath this is cake, because it is not the same size, so even if not notified of this bathtub, but the contents of soalnya we can know.
Because the rod-shaped volume of the formula we used is the beam volume formula v = pxlxt
From the problem that we can over the length = 80 cm, width = 60 cm and 40 cm high, the volume is
V = l x p x t
= 80 x 60 x 40 = 192,000 cm3
Means that the contents or bath tub is the volume of 192,000 cm3.
Because the speed of the contents so we koversikan liter unit volume that we can to the liter, where 1 liter = 1 dm3
Because the liter equal to dm cm3 then we have made to dm3

From the stairs over we can see that from cm3 to dm3 increase of 1 child in 1000 so that the divided
Volume = 192,000 cm3: 1000 = 192 dm3
Because the 1 dm3 equivalent to 1 liter, so
Dm3 volume = 192 = 192 liters.
So, full bath volume is 192 liters, if the speed contents 4 liters a minute then the time required is:
Time = 192: 4 = 48 minutes
So the time to fill the bathtub full speed with an average of 4 liters / minute is 48 minutes.

That is one way a matter of completing the story
