David was making a new door for his house. He found the measurement of the width to be 67 cm. The height of the door was twice the width. In order make his cuts exact he needs to use millimeters. How many millimeters will he need to measure for the height of the door?

13 mL
What is the difference between mass and weight?
Weight is the measurement of the amount of gravitational force on an object whereas mass is the amount of matter in the object.
You will weigh much different on the moon whereas your mass will be the same.

19.3 g/cm3
Define the three variables we use in experiments.
Independent variable- the thing that is changed or manipulated (the thing being tested)
Dependent variable- the thing that is measured (is the effect of the independent variable)
Constant variable- Things that are kept the same throughout the experiment to keep the test valid
