Problems:

1.    A solid rectangular substance from the planet Bucklonia measures 6 cm. high, 2 cm. wide,
       and 8 cm. in length.  Its mass has been determined to be 864 grams.  Be certain to show all
       appropriate formulae and units in your calculations below.

      (a.)  Find the volume of this object.   (5 pts.)
 
 

      (b.) Find the density of this object.   (5 pts.)
 
 
 
 
 

2.  You find an unknown object of irregular shape and believe it has a density greater than that of
     water.    You decide to design a laboratory activity to test your beliefs.    Please write up this
     lab activity design in the space below and include in your description the following.
     (point values for each part follow the requirements below)

• a correctly worded hypothesis stating your belief about the density of this object  (4)
• a list of materials you will need to complete this experiment  (4)
• a procedure including at least five steps explaining how you will obtain the volume and mass of this object  (10)
• an explanation of how you will use this data to compute the object's density  (4)
• an explanation of why it is important that you run as many trials of this experiment as possible  (2)
