Your Answer:

Question 6

You invent a new unit system called the Blerg Unit System. The relationship between your unit system and other units are summarized below:

1 blah = 1.750 meters

1 blop = 4.95 pounds

1 kapow = 11.2 liters

1 gallon = 3.785 L

You decide to convert all of your daily measurements to your new units. Assume you use 18.1 gallons of water when you shower. Convert this volume to kapows and report your answer with the correct significant figures. [Hint: you may not need all of the above unit conversions.]

Your Answer:
